DirectPhotonics lands first 2-kW direct diode laser order

DirectPhotonics Industries, a maker of ultrahigh brightness direct-diode lasers for material processing, has received its first order for the 2-kW DirectProcess laser from a unnamed German research firm. The laser is designed for industrial metal cutting and welding of steel and non-ferrous alloys.

Berlin, Germany--DirectPhotonics Industries, a maker of ultrahigh brightness direct-diode lasers for material processing, has received its first order for the 2-kW DirectProcess laser from a unnamed German research firm. The laser is designed for industrial metal cutting and welding of steel and non-ferrous alloys. Previously the company had several orders from customers in Europe and North America to supply 500-W and 1-kW versions of the DirectProcess product line, shipments of which are expected starting in the second quarter of this year.

The DirectProcess fiber-coupled laser system generates an optical power of 2 kW ex fiber in the 930-nm region with a beam parameter product of 7.5 mm-mrad. The optical output power can be modulated up to 50 kHz with a rise and fall time of less than 10 µs. The DirectProcess laser comes in a 19-inch rack mount and is cooled with standard industrial water.

The DirectProcess product series is based on several patents on power scaling of single-emitter laser diode systems with ultra-high brightness as needed in macro material processing. Stefan Heinemann, CTO of DirectPhotonics, said, “We are proud to ship our first kW lasers only 20 months after the start of our company.”

High brightness, direct diode lasers have been a hot topic recently. TeraDiode, based in Wilmington, MA, is also developing a multi-kW laser based on a related technology.
