2 Brilliance DIAMOND K-Series and G-Series lasers feature Brilliance, a combination of mode quality, peak power, and optical rise-and-fall times. With Brilliance, DIAMOND lasers perform the same tasks as lasers whose continuous-wave (CW) output power is two to three times greater. Brilliance also allows faster and cleaner materials processing than lasers of comparable power. The first characteristic of Brilliance is mode quality. The better a beam s mode quality, the smaller its focused spot. A smaller focused spot results in faster and cleaner processing. The instantaneous power of a laser pulse is the second characteristic of Brilliance. A DIAMOND laser whose average output power is 500W has a peak power of over 1.5 kw. The result is faster ablation of materials. Third, superior optical rise-and-fall times measure how quickly the laser s optical pulse reaches full power and then shuts-off. Short rise-and-fall times create a square-wave pulse profile that generates a smaller heat-affected zone (HAZ) in the processed material. DIAMOND lasers with Brilliance process materials cleaner and more efficiently than any other commercial CO 2 laser.

The GEM-QS patented intra-cavity, electro-optic modulation technology produces multi-kilowatt peak-power pulses with extremely short pulse widths (<150 nanoseconds FWHM). By processing materials in the nanosecond region, Laser Trigger For example, higher average powers can over-process one component (such as epoxy) and under-process another (such as glass). Cutting-Edge Photon energy creates precise Integration features. Technology Creating highly precise, miniature features in materials requires the accurate control and delivery of laser light.

Designed for ease of integration, even in the toughest industrial environments, GEM-Series lasers, available either air-cooled or liquidcooled, also provide the highest output power per unit volume of any commercial sealed CO 2 laser. Rugged, ultra-compact construction exceeds OEM integration requirements. Coherent s patented RF-excited, folded-waveguide technology, today s most rugged CO 2 laser, produces the highest output power per unit volume of any sealed, commercial CO 2 laser. These robust, ultra-compact lasers are easily integrated into the most demanding space-limiting applications. Unlike CO 2 laser cavity designs based on a long tube, GEM-Series lasers use a patented folded-waveguide design that minimizes laser size while maximizing laser power. A further benefit of this design is that it offers highly efficient heat extraction, allowing the laser to be air-cooled or liquid-cooled. cooled or liquid-cooled. Easy, economical integration with air-cooling. Folded-waveguide technology maximizes flexibility, allowing GEM-Series lasers to be air-cooled. Air-cooled units, equipped with fans and a heat sink, have low facilities requirements and minimal service needs. They are also easy to integrate and inexpensive to operate. Environmental resistance with liquid cooling. Environmental considerations and pulsing capabilities are critically important in some system applications. Low-cost is critical in others. Liquid-cooled GEM-Series lasers, resistant to ambient temperature and humidity conditions, are ideal for tropical or desert climates. And they are immune to high-dust conditions, which can clog and incapacitate air-cooling fans. Liquid-cooled GEM lasers also offer both pulsed output capability (up to 25 khz) and greater power stability (±3%). Maximum uptime and maintenance-free operation. Fast and efficient cooling of the lasing gas mixture in the GEM-Series eliminates the need to continuously circulate consumable gas through the cavity. All-metal seals in the head ensure that the permanently confined lasing gas mixture needs no replenishment/ replacement for up to 25,000 hours (>2 years). DIAMOND GEM-30

8 K-Series & G-Series Cutting-Edge Integration Technology Fast materials processing Low cost of ownership Maximum uptime Rugged construction User-friendly Easy to integrate 10.6 µm and 9.4 µm output wavelengths Compact OEM and non-oem configurations Clean, fast and efficient material removal with minimal heat-induced damage. Each pulse from a DIAMOND laser has a square-wave profile with fast rise-and-fall times. Material processing is efficient, cuts and drilled holes are clean, and the heataffected zone (HAZ) is minimal. DIAMOND lasers also feature a set of unique characteristics called Brilliance. Brilliance is a small spot size, high-peak power, and fast rise-time high-frequency pulses. DIAMOND lasers with Brilliance allows faster materials processing while using less power. Systems integrators and industrial endusers have made DIAMOND K-Series and G-Series slab discharge lasers their choice for integration into automated materials processing systems. Using RF-excited, slab-discharge and diffusion-cooling technologies, K-Series and G-Series lasers deliver high-frequency pulsed output and high average-power in a compact, no-maintenance package. Easy installation on moving gantries or within compact materials-processing stations. Slab-discharge technology uses two rectangular plate electrodes to create an efficient, high-power laser that is remarkably robust and compact. For example, a typical 500-watt DIAMOND slab-discharge laser measures only 11 x 9.5 x 47 in. (27.9 x 24 x cm). Selective material removal for precision processing applications. Removing adjacent materials having different ablation thresholds is critically important in applications such as printed circuit board manufacturing. DIAMOND RF amplifiers distribute the energy within a single pulse, or series of pulses, enhancing selective material removal. Thus, it is possible to drill holes in dielectric or polymer materials to a controlled depth, without causing collateral heat-induced damage to an underlying layer. Pulse Tailoring Up to 25,000 hours of continuous, maintenance-free operation lowers the cost of ownership. In slab-discharge lasers, the permanently confined lasing gas mixture functions for up to 25,000 hours (>2 years). Slab-discharge lasers also have far lower facilities requirements, resulting in maximum uptime, inexpensive operation, and increased productivity. Power Time

9 K-Series & G-Series continued... K-Series Lasers Fast and economical materials processing. DIAMOND K-Series lasers compete with flowing-gas CO 2 lasers having much higher average power. Brilliance makes fast materials processing possible. In many applications, K-Series lasers process materials as fast as multi-kilowatt systems. And, far more efficiently and economically. K-Series lasers also feature output wavelengths of either 9.4 or 10.6 microns. G-Series Lasers For simple and flexible integration. Designed for systems integrators, DIAMOND G-Series lasers provide all the benefits of the K-Series in a lower power, low-cost, OEM configuration. To simplify integration and further reduce the size of the G-Series, the head and power supply is manufactured as a single unit. The integrated RF power supply and laser tube can be oriented vertically or horizontally. A built-in optical rail (a component mounting structure) allows beam delivery assemblies and electro-optic accessories to be mounted directly on the laser. Space efficiency and flexibility allow system integrators to create the most economical and compact systems possible. Compact, Efficient Slab Resonator
