SAN JOSE, Calif., Feb. 13 /PRNewswire/ -- SDL, Inc. (NASDAQ:SDLI) today
announced the demonstration of high power blue ultraviolet semiconductor
lasers based on gallium nitride. The new lasers have been demonstrated at
multiple wavelengths between 400 - 410 nm at pulsed powers in excess of 150 mW
per facet. The achievement is an important step in realizing a new class of
compact blue, green, and ultraviolet semiconductor laser sources.
"We are very excited about this demonstration since we believe this
material system has the potential to produce high power lasers with high
reliability over a range of violet to green wavelengths," said Donald R.
Scifres, president and chief executive officer. "We believe the pulsed power
levels recorded by SDL are higher than any reported previously for gallium
nitride-based semiconductor lasers. Such semiconductor lasers are ultimately
expected to see widespread use in applications such as optical data storage,
printing and displays."
SDL is pursuing the technology with matching funds from the Defense
Advanced Research Projects Agency (DARPA) through the Blue Band II Consortium.
The program teams SDL with HP, Xerox and five universities, with the intent of
commercializing single spatial mode blue laser diodes in 1999. |
