Coherent showcases CW green lasers at Photonics West
Compass 415M and 315M Lasers featured alongside a new blue solid-state laser prototype
Coherent Laser Division (CLD; Santa Clara, CA) showcased its Compass 315M and Compass 415M continuous-wave lasers at Photonics West (San Jose, CA; Jan. 22-26). Diode-pumped solid-state (DPSS) lasers that emit at 532 nm, the Compass 315M and 415M are ideally suited for use in markets ranging from reprographics and printing to wafer inspection and bioinstrumentation.
Coherent offers the Compass 315M in output powers of 20-, 50-, 100-, and 150-mW, while the Compass 415M is a higher-power extension to the 315M and is available in 200 mW and 300 mW versions. Both lasers are conductive cooled, feature a TEM00 beam profile and use an intra-cavity frequency doubling crystal to convert IR emissions to the green wavelength.
"Specifically tailored in power and wavelength for the commercial marketplace, our Compass lasers currently dominate applications such as computer-to-plate digital printing and DNA sequencing," said Torsten Rauch, product line manager at Coherent. "They feature a modular OEM design and incorporate Coherent's unique Permalign technique—a system where every component within the laser head is aligned with precision external tooling and then soldered into place. This allows us to build a highly stable, low-noise laser."
Compass 315M and 415M lasers can also be coupled with Coherent's newest laser, the OPSL, an optically pumped semiconductor laser that emits in the blue region, to provide users with a unique green/blue wavelength combination. A prototype of the OPSL is also showcased on the booth at Photonics West. "Our new blue/green offering is especially exciting for the display and photofinishing markets, where RGB sources are needed. The Compass and OPSL tandem will offer the blue and green part of this source in all-solid-state technology," said Rauch.
According to Greg Niven, business development manager for CLD's Graphic Arts Market Business Unit, "The Compass 315M and 415M lasers are based on Coherent's foundation of over 15 years' experience manufacturing diode-pumped lasers. It is this experience that translates into highly robust, reliable products that are at the heart of our current shipment rate of more than 3,000 DPSS lasers per year."
Founded in 1966, Coherent Inc. is a Standard & Poor's SmallCap 600 company and a world leader in the design, manufacture, and marketing of lasers and systems for commercial, scientific, medical, and telecom markets.
