Also Announces New 879 nm and 793 nm Laser Diode Products with Wavelength
Stabilization Technology for Higher Output without Compromising Industry’s Best
Reliability

MADISON, WI– January 19, 2010 – Alfalight, Inc., a leading supplier of highlyefficient,
high-power laser diodes, announced today the availability of the 808C laser
diode series of 3.5 W, 808 nm devices in a 6-pin package with a 105 µm/0.15 NA output
fiber. The new devices extend Alfalight’s 808 nm offering with a 40% increase in output
power while maintaining an unrivaled lifetime of 20,000 hours. The series includes a 3 W
version integrating Alfalight’s proven Wavelength Stabilization Technology (WST),
which offers 0.07 nm/°C wavelength stability – a factor of five more stable over
temperature than standard semiconductor lasers. WST eliminates the need for precise
temperature control for solid-state laser pumping and other spectrum-sensitive
applications. The company also announced additional new WST products at other
increasingly important wavelengths, including a 30 W, 879 nm combined power module
(CPM III) with 685 µm/0.22NA output fiber connector; and a 5 W, 793 nm 6-pin laser
with 200 µm/0.15NA fiber. The new products will be on display at Photonics West
(Alfalight booth 2038), January 26-28.

“Alfalight offers a significant increase in output power at 808 nm with no compromise on
our proven reliability standards,” said Ron Bechtold, vice president, sales and marketing
at Alfalight. “Across the board, we continue to support customer needs with the timely
development and manufacture of cost-competitive, robust and high-brightness diode laser
systems that benefit fiber lasers, solid state lasers and direct diode applications.”
