28 Jan 2008 High-Reliability Single Emitter Pumps Leverage SHEDS Development Advances for Industry-Leading Power and Efficiency A new series of laser pump diodes from Alfalight Inc., the AM6-808B and AM6-808BW, provides 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 from Pacer International and production volumes will ship in March of 2008. Pricing is available on request. Part numbers are AM6-808B-60-503 for the 5 W 808±3 nm Standard version and AM6-808BW-60-501 for the 5 W 808±1.5 nm WST version. |
