nLIGHT Displays High-Power, Fiber-Coupled Industrial Lasers at Photonics West

Vancouver, WA USA  January 15, 2008 – For the first time at Photonics West, nLIGHT Corp., in collaboration with Optotools GmbH, will display fiber-coupled diode lasers that offer both high power and beam quality in a format suitable for industrial applications. The nLIGHT OTF Modules and the OTF HP systems represent a new approach to direct diode laser processing, combining advanced optics with the latest generation of high-power laser diodes in a reliable, conduction-cooled format. To see the OTF Module, please stop by the nLIGHT booth, number 1806 at the Photonics West trade show in San Jose, January 22 - 24, 2008.

“Recent advances in the brightness and power of high-power laser diodes, along with beamforming techniques utilized in these new products enable precision industrial applications such as plastic joining and soldering to be realized in compact, affordable systems,” commented Joe DeBartolo Vice President of Sales and Marketing. “At the kW power levels, the nLIGHT/Optotools lasers will enable applications in welding, brazing and heat-treating systems previously not within the reach of direct-diode technology. When comparing these laser sources, direct-diode technology offers the highest efficiency and reliability with the low maintenance cost and small form-factor that leads to a lower cost of ownership."

The OTF Module combines the proven reliability of conduction-cooled diodes with advanced beamforming technologies to create a robust, industrial, fiber-coupled laser source. This modular design offers significant flexibility, and with the integrated monitoring electronics, open interfaces, and options for high-power industrial cables, pilot beams and shutters, the OTF Module redefines the direct-diode category with features, performance and reliability not previously available.

The OTF HP system leverages the modular design of the OTF fiber-coupled source, plus the integration of the power supply, chiller and beam combining optics to deliver a fully self-contained system at kilowatt power levels in a compact footprint. This maintenance-free reliability, small size, and higher efficiency, combined with a lower up-front cost, leads to a dramatic reduction in the overall cost of ownership when compared to conventional lamp-pumped systems, opening up new paradigms in material processing markets such as welding, brazing, cladding and hardening.
