Lambda introduces PowerGator laser

May 16, 2001 – Fort Lauderdale, FL – Lambda Physik has introduced its PowerGator 532-15, the latest in the company’s series of industrial-grade DPSS lasers. The company said the new laser delivers over 13.5W average power and up to 50GW/cm2 peak power intensity, the system microfabricates high aspect-ratio features in hard materials over 1mm thick.

Short 15ns pulses and 532nm (green) improve plasma penetration for high aspect ratio microfabrication, according to Lambda. These features reduce heat-induced affects, microcracking and redeposition of material, yielding higher quality surfaces and features deeper than longer pulse Green, UV and IR systems, the company said. High beam quality allows focusability for feature sizes below 20 microns.

According to Lambda, application results show this short nanosecond pulsed, higher peak power – visible wavelength laser produces surface quality comparable to longer pulsed UV laser processing in ceramics, silicon, and metal alloys. At 10,000 Hz pulse rate, microfabrication production times exceed conventional electro-chemical, electrical discharge machining and UV laser systems for feature sizes as small as 20 microns and thickness over 1mm.

All Gator Series lasers are OEM grade and designed for 24-hour production demands, the company said. Featuring a hermetically sealed laser head, RS 232 function control for complete hands-free operation, and remote/removable supply unit, these lasers deliver optimal ‘process-up-time’ with rated MTBF between 10,000 and 20,000 hours, Lambda claimed.
