20 Uncoated Optical Windows/Substrates Description Various dimensions substrates made from BK7, UVFS, IRFS, CaF 2, ZnSe, Sapphire, MgF 2. Standard substrates are laser grade polished on both surfaces. These substrates are ideal for beamsplitters, windows, partial reflecting mirrors etc. Laser components require highly polished substrates as well as high performance coatings. Scattering, damage of laser light can occur if the substrate is made of inferior material or if it is inadequately polished. For UV, very high power applications and ultrashort pulses we recommend using UVFS substrates. BK7 substrates are economical solution for laser components used in many applications in laboratory as well as in devices and instruments. Altechna provides various dielectric and metallic coatings on optical substrates.

22 Precision Uncoated Optical Windows/ Substrates Description Being designed as precision windows/substrates to distinguish by supreme surface polishing quality as well as surface flatness and parallelism, which makes the windows indispensable article for most precision demanding applications. Special polishing technique is used to drive surface smoothness and flatness nearly to perfection. This product is ideal substrate to produce mirrors/polarizers for high power applications since laser induced damage threshold (LIDT) value is closely related to surface polishing quality. Negligible parallelism error (<5arcsec) causes minimum misalignment errors, when component is repeatedly inserted and removed, this particular property makes it first choice item when one needs substrates for beamsplitters and thin film polarizers with minimal beam deviation. Features Superior polishing quality (10/5 Scratch/Dig) Negligible parallelism error (<5arcsec) Ideal for low scatter demanding applications Same polishing quality applies to both surfaces Minimum misalignment errors when window is repetitively inserted and removed Standard specifications Material BK7 and UVFS (Corning F grade) Diameter/dimensions tolerance +0/-0.1 mm Thickness tolerance ±0.1 mm Clear aperture >90 % Surface quality 10-5 S-D Transmitted wavefront distortion (TWD) <λ/10@632.8 nm Parallelism error <5 arcsec Protective chamfers <0.25 mm x 45 Coatings Call us 22

38 Powell Lenses Description The Powell lens has an advantage over cylindrical lenses because later one produces a poorly illuminated line, limited by the non-uniform Gaussian laser beam. Huge spherical aberration redistribute light along the line, decreasing the light in the central area while increasing the light intensity at the line s end. The outcome is uniformly illuminated line used in all manner of machine vision applications.

40 Achromatic Lenses Description Cemented achromatic duplet lenses are optimized to provide excellent chromatic and spherical aberrations free performance. Optimized composition of two lenses, where one is made of dense flint and second of crown glass, assures much tighter focus than singlet spherical lenses due to minimized longitudinal and transverse spherical aberrations. They also feature nearly constant focal length across wide range of wavelengths. Standard achromatic duplet lenses cover two ranges visible (400 nm 700 nm) and near infrared (700 nm 1050 nm). Single line, dual line and different than standard broadband configurations are also available.

44 Plano-Convex Axicons (Conical lenses) Description Plano-convex axicons are conical lenses which are used for variety of applications. When followed by a conventional spherical lens, axicons can focus laser light to a ring shape with annular focus. This feature can be used in hole drilling, microscopy and medical applications. Another interesting feature of axicons is a possibility to transform Gaussian beam into non-diffractive Bessel beam in the near field. Bessel beams can be used in atom or molecule guiding applications. Altechna offers two types of plano-convex axicons: regular and precision. Regular axicons will create annularly shaped beam whereas precision axicons will also transform Gaussian beam into a Bessel beam. You can choose accordingly, depending to your specific application.

46 Plano-Concave Axicons (Conical lenses) Description Plano-concave axicons have a plano surface in combination with a concave conical surface. Concave axicon produces a ring shaped image along the axis from a point light source (e.g. Gaussian laser beam). Due to specifics in fabrication process, a hole in the center of concave surface is needed. Diameter of the hole is typically 1 mm. Different coatings can be applied on the polished surfaces of axicons. When coated with HR coating, concave conical surface can be used as a conical mirror in some specific applications.

50 Right-Angle Prisms Description Right angle prisms are used to direct beams at 90 degrees by using the hypotenuse face for total internal reflection (TIR). These prisms are often preferable to an inclined mirror in applications involving severe acoustic or inertial loads, because they are easier to mount, and deform much less than mirrors in response to external mechanical stress. As long as acceptance angle limitations for TIR from the roof faces are not exceeded, the right angle prism can also serve as a retroreflector, reflecting a beam back.

53 Corner Cube Retroreflectors Description Corner cube retroreflectors are designed to deviate incident light by 180 degrees independent of the angle of incidence. These prisms have 3 mirror surfaces making angles of 90 degrees to each other, juxtaposed to form the corner of a cube with the entrance face perpendicular to cube diagonal. All beams, independent of the direction of incidence, are reflected back. Corner cubes are used for high precision applications or with lasers working in very long distances.

54 Dielectric Coatings Description Dielectric coatings consist of layers with different refractive indices. There are three major techniques used for dielectric coating: electronbeam deposition (E-beam), ion-assisted electron-beam (IAD) and ion beam sputtering (IBS). All of these processes are quite similar in their principle. They consist of evaporating some coating material and deposit it on the substrate. The difference lies in the deposition energy. Because of low energies involved when using electron-beam deposition, thin film contains bubbles and micropores like a sponge. These will eventually fill with water, which will change the refractive index of the coating and thus the properties of the optics. (This is known as environmental shifting ). The presence of water also lowers the damage threshold of the optics: when exposed to an intense light, the water will tend to vaporise and dislodge off bits of the coating. Finally, even in the absence of water, inhomogeneities of coating layers decrease the theoretical damage threshold. The positive points about this technology is that it is cost effective, widespread and very versatile. The coating itself is also slightly flexible, which makes the optics more resistant to mechanical stress. Ion-assisted electron-beam is an intermediate technique, between ionbeam sputtering and E-beam. So are its results. Ion beam sputtering involves energies 100 times higher than E-beams. As a result the molecules of the coating layers form covalent bound when deposited. The resulting coating is free from bubbles or pores, more homogeneous, more durable, has higher damage threshold and is more repeatable and controllable. It also exhibits lower scattering and absorption properties, and overall higher specifications (more broadband, steeper transitions when needed, better spectral stability ). This is high precision coating, and the surface roughness can be controlled at better than 1 Å RMS (!), that is <λ/5000. Of course, this comes at a higher cost (atom-by-atom removal is very slow), and even worse, it is limited in the types of coatings it can handle: most of the UV coatings for instance involve fluorides which dissociate when sputtered. In this case, E-beam is the only option. Each coating is special and over the years in the photonics field we have learned that flexibility is the key to meet high demands of our customers therefore our coatings are done using different technologies which are chosen for separate coatings individually. Here is our list of coating technologies available at Altechna Electron beam evaporation Ion assisted deposition Ion beam sputtering Each technology is different and is used according to requirements of spectral sensitivity, damage threshold, hardness, surface quality etc. Electron beam evaporation Ion assisted deposition Ion beam sputtering Deposition Rate >10 Å/sec ~10 Å/sec ~3 Å/sec Coating area per run 3000 cm cm cm 2 Thermal Conductivity Low Medium High Temperature Range During Coating C C C Number of Layers 1-50 ~ Density / Porosity Porous Dense Near bulk Adhesion / Durability Low Good Excellent Humidity Sensitivity Yes Yes, small No Aging Effects Yes Yes, small No Intrinsic Stress < 100 MPa ~ 100 MPa Few 100 MPa 54

55 HR Laser Line Mirrors (HR) Description HR laser line mirrors (HR) provide optimized performance at certain wavelength and certain angle of incidence (AOI). Mirror consists of substrate and multilayer coating stacks which help to achieve very high reflectivity at specific laser line wavelength at any designed angle of incidence. Laser line HR coatings are used for external beam manipulation applications where even slight losses may be intolerable. Coatings are provided by electron beam evaporation with/without ion assistance coating technique. E-beam HR coatings are the most common dielectric coatings in laser optics market as this technology was leading for few decades, and only in recent years this technology started facing competition from other technologies.

57 Low Loss HR Mirrors Description Low loss mirrors are also referred to as IBS mirror due to ion-beam coating technology. The mirrors provide maximum reflectance at certain wavelength range and certain angle of incidence (AOI). IBS technology stands out by multiple advantages against other coating techniques. Due to fully automated control of deposition process coatings distinguish by high repeatability, sharper features, tighter tolerances. IBS thin films feature higher density, durability, high-damage-threshold, impenetrable to water vapor, which make them resistant to environmental conditions such as heat, humidity and pressure. IBS coatings distinguish by nearly all specification being supreme to the ones provided by other coating technologies. It allows to minimize scatter in the dielectric layers which is limiting factor, then reflectivity higher than 99,9 % is targeted.

63 Non-Polarizing Plate Beamsplitter Non-polarizing beamsplitting plates exhibit a polarization insensitve performance. Description In comparison to non-polarizing beamsplitter cubes, our plate beamsplitters feature outstanding performance. Cubes typically cause loss of at approximately 10 %, because of absorption in hybrid coatings. At the same time laser induced damage threshold scales in range of approximately 0.3 J/cm 2. Non-polarizing beamsplitting plates are coated with only dielectric layers, thus damage threshold is much higher and exceeds 6 J/cm 2. Separation of polarizations Rs - Rp typically is lower than 5 %. Because of this feature beamsplitters are suitable for use with unpolarized light or light of any other state of polarization. Standard items have a decent working bandwidth of several tens of nanometers, what makes them usefull for several lasers. For example 1-OS [4G45-50] beamsplitter (Rsp= nm nm) can be used with Yb:KGW, Yb:YAG, Nd:YAG, Yb:Glass, Nd:Glass lasers. For usage with femtosecond lasers, Altechna has designed 1-OS [4F45-50] and 1-OS [4C45-50] beamsplitters, which do not influence pulse width, as coatings are GDD compensated. Custom size configurations and non-standard wavelengths are also available.

65 Low GDD Ultrafast Mirrors Description Low GDD Ultrafast mirrors are designed for femtosecond applications to provide an optimized performance at certain wavelength and angle of incidence (AOI). This is achieved by careful selection of coating stacks to combine high reflectivity and low GDD value (from -10 fs 2 to 10 fs 2 at design bandwidth) at the same time. Such coatings are used for external beam manipulation applications where pulse broadening effect is undesirable. Low GDD Ultrafast mirrors are intended for Ti:Sapphire, Nd:Glass, Er:Glass or Ytterbium doped host based lasers working in femtosecond regime. Variety of catalogue components allows to choose the right mirror for fundamental wavelength as well as for it s harmonics.

68 Laser Output Coupler Description Output coupler (OC) is a partially reflecting dielectric mirror used in a laser cavity. It has a function to transmit a part of intracavity optical power in order to get a lasing. Output couplers listed below can be found in stable resonators, as they have a spatially constant reflection/ transmission (R/T) value, which is the main property of such kind of mirror. Such cavity s parameters as pump power threshold, maximum output power and laser efficiency highly depends on R/T ratio of output coupler. Thus choosing a right output mirror for a cavity design is quite a crucial moment. For user s convenience Altechna maintains commonly used output couplers for high intensity intracavity use. Rear surface is antireflective coated in order to minimize Fresnel reflections. Concave mirrors help to maintain TEM00 spatial mode within the resonator while wedged mirror deflect Fresnel reflection that could be amplified within resonator and form secondary (parasitic) pulse.

92 Right Angle Prism Mirror Description When precise and rigid mounting of bending mirror is needed, right angle prism mirrors provide more advantage than plate mirrors. Mirrors are designed to reflect light that is externally incident to hypotenuse of the prism. Prism angular tolerance of 90 deg angle is in range of several arc minutes (or arc seconds for precision type). Easy mounting does not required further alignment to bend a light at exact 90 deg angle, what makes the mirrors ideal for rigid optical systems. Four standard metallic coatings are provided. The most common is aluminum coating which features a fair reflection in UV, visible and mid - IR wavelength ranges. Other type of aluminum coating is labeled as UV enhanced, which means it is designed for UV applications. Protected silver coating is best suited for application in visible wavelength range, while protected gold is the most efficient coating over the entire IR range. However, for maximum reflectivity and highest LIDT, the best choice is dielectric coated mirrors. Altechna provides wide range of standard design dielectric coatings, but custom coatings are also available.

106 Waveplates (Phase Retardation Plates) Brief Overview Linearly polarized input 45 Input polarization plane Emergent beam is circular polarized ALTECHNA offers wide range of zero order (ZO), low order (LO) half (λ/2) or quarter (λ/4) waveplates for UV, VIS, NIR and IR (for any wavelength in nm range). Waveplates are made from materials which exhibit birefringence. The velocity of the extraordinary and ordinary rays through the birefringent material varies inversely with their refractive indices. This difference in velocities gives a rise to phase difference. At any specific wavelength the phase difference is governed by thickness of the waveplate. Half (λ/2) waveplate. A linearly polarized beam incident on a half wave crystal quartz waveplate emerges as a linearly polarized beam but rotated such that its angle to the optical axis is twice that of the incident beam. Therefore, half-waveplates can be used as continuously adjustable polarization rotators. Half-waveplates are used in eletrooptic modulation, as a variable ratio beamsplitter when used in combination with a thin film polarizer or polarizing cube, or in general to rotate the plane of polarization. Quarter (λ/4) waveplate - thin-film compensator. If the angle between the electric field vector of the incident linearly polarized beam and the retarder principal plane of the quarter-waveplate is 45 degrees, the emergent beam is circularly polarized. When a quarter waveplate is double passed, i.e. by mirror reflection, it acts as a half waveplate and rotates the plane of polarization to a certain angle. Quarter waveplates are used in creating circular polarization from linear or linear polarization from circular, ellipsometry, optical pumping, suppressing unwanted reflection and optical isolation. Features Waveplates for any wavelength in the nm range Air-spaced ZO waveplates for high energy applications Waveplates for many wavelengths are available from stock Custom design waveplate assemblies are available on request Linearly polarized input Miscellaneous Performance of quarter (λ/4) waveplate Input polarization plane Crystalline optic-axis direction Crystalline optic-axis direction Performance of half (λ/2) waveplate Zero order (ZO) waveplates are generally preferred since they are least sensitive to variations in wavelength, angle of incidence and temperature. To suit different applications, air spaced or optically contacted (see drawings on next page) Zero order compensated phase retardation plates are available from Altechna The air-spaced construction enables to use the waveplate for high power laser applications. The damage threshold is more than 10 J/cm 2 for Crystalline Quartz Waveplates, more than 20 J/cm 2 for High Power Waveplate and more than 5 J/cm 2 for Achromatic Waveplates. 2θ Output polarization direction 106

107 Crystalline Quartz Waveplates Retardation vs. wavelength for ZO and LO crystalline quartz waveplates Description Altechna is offering a wide range of zero order (ZO) and low order (LO) waveplates for UV, VIS, NIR range (for any wavelength in nm range). All waveplates we provide are made from excellent quality laser grade crystalline quartz material. ZO waveplate is constructed by two quartz plates with their fast axes crossed. The difference in thickness between the two plates determines the retardance. ZO waveplates offer a substantially lower dependence on temperature, angle and wavelength change than conventional monolithic LO waveplates. To suit different applications, air-spaced or optically contacted ZO compensated phase retardation waveplates are available from Altechna. The air-spaced construction enables to use the waveplate for high power laser applications.

111 Achromatic (Broadband) Waveplates Description An achromatic waveplate (AWP) is a pair of crystal quartz and magnesium fluoride plates. Because of the difference in dispersion in these uniaxial positive crystals it is possible to calculate thickness of each plate so that birefringent phase shift in assembly changes very slowly over a certain wavelength range. This is a way to obtain achromatic zero order waveplates. Such AWPs are necessary for various devices and may replace a number of ordinary quartz waveplates operating at a single wavelength only. We can offer series of Achromatic Waveplates with phase shifts shown in graphs below.

116 S-waveplates S-waveplate is a super-structured waveplate which converts linear polarization to radial or azimuthal polarization. Product is unique for its high damage threshold 10 times exceeding alternative devices: according to ISO is θ 1000-on-1 = ± 2.74 J/cm 2, at (λ = 1064 nm, τ = 3.5 ns, f = 10 Hz) S-waveplate is fabricated inside UVFS bulk. Benefits Radial polarization enables focusing of laser beam into smaller spot size (high numerical aperture, NA>0.9 optics). Focused azymuth polarization remains ring shaped. For polarization direction sensitive applications radial/azimuth polarization allows same machining properties in all directions. It is also applicable in optical tweezers, STED microscopy or any other depletion application.

117 Custom Polarization Converters Description Custom birefringent patterns (half-wave or quarter-wave) for tailored polarization conversion. We control retardance and slow axis angle according to the predefined function. We offer custom polarisation converters for various polarization and beam shaping applications: radial polarization, azimuth polarization, random polarization, circular polarization, elliptical polarization, custom polarisation, optical vortex generation, flattop generation. Production of custom polarization converters is based on unique laser nano-structuring technique developed by prof. Peter G. Kazansky group from Optoelectronics Research Centre at Southampton University. Converter shown in cross-polarized light at different incident polarization angles Features Wavelength range from 400 nm to 2000 nm Half-wave or quarte-wave converters available Size from 1 mm to 10 mm Transmission from 40% to 90% (* wavelength dependent) Custom birefringent patterns Converted beam (532 nm) intensity at different incident polarization angles 117

118 Polarization Rotators Description Polarization rotator is a good alternative to retardation waveplate when it comes to rotation of polarization at certain angle. Polarization rotation is caused by property, called Optical activity, which is natural to quartz crystal and other substances that are enantiomorphous. This property is caused by crystal lattice structure, that lacks mirror symmetry due to helicoidal chains of SiO 4 units oriented along c-axis in quartz structure. Depending on chain rotation direction, there is right and left quartz which rotates polarization clockwise or counterclockwise respectively. Polarization rotators are c-cut so rotation of polarization occurs independently of component s rotation around optical axis, thus component is alignment-insensitive and the only requirement is that incident beam must be perpendicular to rotator s aperture. Altechna offers rotators with fixed 45 deg or 90 deg rotation of polarization with antireflection coatings for design wavelength. For convenient use all rotators are mounted in black anodized aluminum mount. Device is good replacement for waveplate, for usage along with narrow band lasers.

153 Yb:CaF 2 Crystals Description Due to Yb:CaF 2 crystal low quantum defect and a comparably long fluorescence lifetime, ytterbium-doped gain media are preferably utilized for high-power diode-pumped systems and laser amplifiers with high optical-to-optical conversion efficiencies. From this point of view, Yb:YAG is now the most important and developed one. Just recently, ytterbium-doped alkaline-earth fluorides (Yb:CaF 2 ) have attracted considerable interest for use in diode-pumped femtosecond (fs) lasers and amplifiers. Alkaline-earth fluorides which can be easily grown by using the standard Czochralski or Bridgman technique show a wide optical transmission range, a low dispersion behavior and limited nonlinear effects under intense laser irradiation. It was recently shown that Yb:CaF 2 single crystal can be grown up to diameters of about 200 mm, which is superior for high-energy short-pulse lasers with centimetersized apertures.

Place polarizers into mechanical adapter. Polarizers must face each other with surfaces coated with polarizing coating. Polarizing coating is marked with an arrow, so you have to put the polarizers with the arrows on the sides facing each other. Then fix polarizers with the plastic bolts (use all 4 plastic bolts to fix one polarizer). NOTICE: do not tighten up the bolts too much since it can bend the polarizer and thus distort the laser beam. Step 2. Put wave plate into attenuator between two mounting rings as shown. Be sure the wave plate is immobilized tightly. Step 3. Attenuator consists of two mechanical parts. You should assemble both mechanical parts together. Step 4. Use fixing screw for tightening both parts together. Manual version of Watt Pilot model costs 750 less than the motorized model found in the catalogue. 179

Air bearing stage and electronic collimator allows to reach less than 0.1 μm accuracy when measuring centering errors. Additional accessories extend our capabilities to measure focal length values up to ± 5 meters, ROC ± 800 mm. Spectrophotometers Spectrophotometers measures transmittance and reflectance from 190 nm to nm. We use special mount to make measurements at angles from 0 to 75 deg in the range from 190 nm to 4900 nm. Integrated polarizers allows to measure spectra for s and p polarizations.
