Outstanding semiconductor material for high-power diode lasers

Thanks to precise controls, our laser bars, semi-bars and single emitters meet the highest quality standards of our customers.

Laser bars

Product feature

  • Wavelength: 760 - 1060nm
  • Output power: 10 - 500W
  • Operation mode: CW / QCW
  • Filling factor: - - 75%
  • Resonator length: 0.6 - 4.0mm

We produce our semiconductor materials under the strictest quality controls. We work only with state-of-the-art epitaxy, processing and facet coating technology. Our bars, semi-bars and single emitters for high-power diode lasers therefore meet the most exacting demands: They are extremely reliable, efficient and durable.

Our semiconductor products are easily assembled using standard soldering methods. The material supports both soft solder (indium) and hard solder (gold/tin). We deliver our laser bars to you with emitter structures separated on the p-side as standard. On request, we can also produce bars with continuous p-side metalization and adapted facet coatings, using low AR coatings for the assembly of external resonators.


  • Highest quality: We strictly monitor the production of our semiconductor products in clearly defined processes.
  • Powerful: High, reliable output power and ideal beam characteristics.
  • Economical: Our semiconductors are very efficient and are characterized by a long service life.


    Fields of Application

    • Industry: Semiconductors for high-power diode lasers in direct material processing, for heating or lighting. Semiconductors as pumping sources for fiber and solid-state lasers. Use in printing technology.
    • Medicine: Esthetics, dermatology and surgery.
