Jenoptik Mounted Laser Diode Bars:

Bars, Mini-Bars and Single Emitters as Passively Cooled Laser DiodesJenoptik Mounted Diode Lasers RPMC Lasers

Product feature

  • Wavelength: 808 – 1470nm
  • Output power: 8 – 300W
  • Operation mode: CW / QCW
  • Cooling: actively cooled / passively cooled

You can choose between cw and qcw operation. We offer standard wavelengths of 808nm, 940nm and 980 nm. On request, we can optimize diode lasers for other wavelengths thanks to the flexibility of our own semiconductor production facility in Berlin. 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.

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.

Each of these laser bars individually supplies up to 120 watts 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.
