You can choose between CW and QCW operation. We offer standard wavelengths of 808 nm, 940 nm and 980 nm. On request, we can optimize diode lasers for other wavelengths thanks to the flexibility of our own semiconductor production facility. You also receive different emission heights in standardized packages. The collimation is available in Fast-Axis (FA) only or in Fast-Axis (FA/SA).

Our patented CN design means that the bars of our mounted diode lasers are cooled on both sides. This means you can achieve thermal resistances that are very close to those of a microchannel heat sink. Our diode lasers also deliver high output power and a low smile. diode laser chip, bar, stack

3. CW Diode Laser Stacks

Up to 12 laser bars to form actively cooled stacks for CW mode.

Our vertical stacks can be used to increase the optical output power of your diode laser. To do so, we stack up to 12 mounted laser bars to form a diode laser stack or an assembly. Each of these laser bars individually supplies up to 120watts in CW mode. Because of the small gaps between the laser bars, you obtain maximum brilliance from the stacks, enabling you to work highly effective. You can choose between laser diode stacks with a Fast-Axis (FA) or combined Fast-Axis/Slow-Axis (SA) collimation. diode laser chip bar stack

4. QCW diode laser stacks

Our passively cooled diode laser stacks and assemblies for QCW operation are highly efficient – even under harsh environmental conditions. We assemble our vertical and horizontal stacks using gold and tin solder (hard solder) as standard. This enables hard-pulse operation under demanding climatic conditions. Because of their lightweight construction, the stacks also easily withstand vibrations and shocks. Thanks to their reliability and efficiency, our diode laser stacks are also used as pumping sources for solid-state lasers, including in the field of high energy research.

As standard, we form passively cooled vertical stacks consisting up to 16 laser elements or arrange up to 4 laser elements in a row. Other configurations are available upon request. You can thus achieve output power up into the kW range. diode laser chip bar stack
