Alfalight Introduces High-Power 5 W 808 nm Pump Diodes With Integrated Wavelength Stabilization for Diode Pumped Solid State Lasers

High-Reliability Single Emitter Pumps Leverage SHEDS Development Advances for Industry-Leading Power and Efficiency

MADISON, WI--(Marketwire - January 21, 2008) - Alfalight, Inc., an innovative manufacturer of highly efficient and reliable high-power diode lasers, today introduced a new series of laser pump diodes, the AM6-808B and AM6-808BW providing 5 W of 808 nm light output with a 200 µm 0.15 NA fiber. The new diodes extend recent Alfalight development advances achieved in the Super High Efficiency Diode Sources (SHEDS) program sponsored by DARPA. The high-reliability single-emitter (SE) laser diodes are available in a 6-pin industrial grade package and include a temperature monitoring thermistor. The diodes are available in both standard (808+/-3 nm) and integrated Wavelength Stabilization Technology (WST) (808+/-1.5 nm) versions. Alfalight's proven, proprietary WST enables tighter bandwidth and a narrow spectrum, and wavelength locking allows uncooled operations over a wide temperature range. Spectral shift for the standard version is 0.3 nm/° C, reduced to 0.07 nm/° C for the WST version. Target markets for the small footprint device include microlasers for projection and display systems; small, high-reliability DPSS lasers; and small-form-factor green lasers.

"The rapid extension of our successful SHEDS and Wavelength Stabilization Technology programs enables us to broaden our offering of innovative, high-efficiency, high-power commercial devices," said Ron Bechtold, vice president of sales and marketing at Alfalight. "Our technology leadership and automated manufacturing expertise allow us to deliver to commercial customers a stream of new devices that offer the highest reliability combined with industry-leading power and efficiency."


The new Alfalight 5 W 808 nm diodes are available in a 6-pin industrial grade package. Engineering samples are available now and production volumes will ship in March of 2008. Pricing is available on request.

5 W 808+/-3 nm Standard version     AM6-808B-60-503

5 W 808+/-1.5 nm WST version        AM6-808BW-60-501
