Micro Machining and Trimming Introduction: Isolators are optical devices that allow light to be transmitted in one direction only. They are most often used to prevent any reflected light from entering the source, thus preventing any feedback problems, such as frequency instability, relaxation oscillations, amplified stimulated emissions, or optical damage from occurring. ith the recent dramatic increase in laser output powers, especially in the 1040-1090 wavelength range, the need to prevent the negative effects of optical feedback into lasers has become critical. To meet this demand OZ Optics has developed a line of high power handling polarization independent isolators, capable of peak isolation levels of 30 to 50 for 1040 to 1090, depending on the input beam size. The isolators are offered with fiber pigtailed collimators on the input beam, with typical beam diameters of 0.8 to 1.1mm. Premium Grade Fiber Pigtailed Collimator to Free Space 1064 Isolator Product Description: OZ Optics uses a patented tilt aligent technique to manufacture isolators with fiber pigtails. Light from an optical fiber is first collimated then transmitted through the isolator. If desired, a similar fiber pigtailed collimator can be mounted on the output end of the isolator for a fiber pigtailed isolator. The fibers can be standard single mode fibers or Large Mode Area (LMA) fibers. LMA fibers are used to reduce the optical power density in the fiber core and therefore allow guidance of larger input power levels while still achieving near-gaussian output beam quality. This patented tilt aligent technique allows OZ Optics to offer compact pigtailed devices, with footprints of 48mm x 86mm or 32mm diameter x 82mm long. In addition the isolators come with built-in windows to prevent dust contamination of internal isolator optics. These protection windows are easily removed and installed by the user OZ Optics also offers receptacle style fiber to free-space isolators as shown in Figure 3, where customers can connect a high power patchcord terminated with an adjustable FC connector as shown in Figure 4. This option gives the user extra flexibility in the control of beam size propagating through the isolator. High Power Isolator with Beam Expander Fiber-Fiber Pigtailed 1064 Isolator 7 www.skphotonics.com
Polarization insensitive isolators use birefringent crystals to separate the input beam into two orthogonal polarizations, transmit them through the faraday crystal and then recombine them to produce an output beam. For maximum transmission, low absorption and high isolation, careful aligent of the internal components with respect to the propagating optical beam is needed. e offer Premium Grade and Standard Grade versions.

OZ Optics can provide these isolators as free-space versions with options for the customer to mount the fiber pigtailed collimator or beam expander at the customer's site. The OZ Optics tilt adjustment technique affords well for customers to perform the optical aligent themselves.

For custom parts, please contact OZ Optics. 1. hat is your input power level? 2. hat is the center wavelength of your source? 3. Do you need a free-space isolator, a fiber-to-air isolator or a fiber pigtailed isolator? 4. Do you need a Premium Grade or a Standard Grade isolator? 5. If free-space type, what is your input beam diameter? 6. If the fiber-to-air type, what type of input fiber do you require: Standard singlemode, polarization maintaining, or LMA fiber. If LMA, please supply fiber specifications -fiber manufacturer's datasheet if possible, core/cladding size, and core & cladding numerical aperture value at the least. 7. For fiber collimator pigtail, do you need 3mm or 5mm OD armor cabled fiber? 8. Do you need a beam expander assembly at the output? If so, what is the required collimated beam diameter? 9. Do you need a connector on the free end of the fiber pigtailed collimator? Please note that in general power handling capability of connectors may not be high as the isolator. For example, we recommend that connectors are only used to facilitate testing of device at low power levels and that fiber is directly fusion spliced to the fiber laser source. 9 www.skphotonics.com
