Reliable QCW diode laser stacks for the harshest climatic conditions

Our passively cooled diode laser stacks and assemblies for QCW operation are highly efficient – even under harsh environmental conditions.

QCW stack

Product feature

  • Wavelength: 808 - 940nm
  • Output power: 270 - 2400W
  • Operation mode: QCW
  • Cooling: actively cooled / passively cooled
  • Collimation: fast axis / without

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.

Benefits

  • Efficient: High output power up into the kW range.
  • Compact: Small and lightweight design is easily integrated.
  • Robust: Shock and vibration resistant.
  • Reliable: Works even under the most demanding climatic conditions.
  • High-quality: We only use hard solder.

Fields of Application

  • High energy research: QCW pumping sources for solid-state lasers.
  • Medical technology: Long-pulse operation, use in esthetics (epilation) and dermatology.
  • Defense: Short-pulse operation, use as a pumping source, for lighting or in LIDAR systems.
  • Industry: Excitation light source for solid-state and fiber lasers.
