Vertical QCW diode laser stack

We use Ausn solder to assemble our Vertical QCW laser stack. This technology makes laser have high reliability even in harsh working environment

Vertical QCW diode laser stack Feature

1. wavelength: 808nm or up on requirement
2. output power: 500w up to 10kw
3. operation mode: QCW
4. cooling: actively cooled / passively cooled
5. FAC avalible


Vertical QCW diode laser stack Benefits:

  1. Customized upon request to adjust pumping structure
  2. Robust: Shock and vibration resistant.
  3. Reliable and high-quality: Ausn solder mounting. Works even under the most demanding climatic conditions.
  4. wavelength combination: beneficial for full temperature pumping design.
  5. Duty circle up to 20%

Vertical QCW diode laser stack Aplication:

  • High energy research: QCW pumping sources for solid-state lasers.
  • Medical technology: Long-pulse operation, use in esthietics(epilation) and dermatology.
  • Excitation light source for solid-state lasers in the 1320nm range for parenchyma surgery.
  • 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.


Vertical QCW diode laser stack Note:

  1. VSQCW-MI/MA-100~500-N. MI represent we use micro channel cooler as a heatsink which need deioned water. MA represent heatsink need passibely cooled or pure water cooled.
  2. VSQCW-MI/MA-100~500-N, 100~500 represent the laser power per bar can be 100w, 200w, 300w and 500w
  3. The above parameters are measured at the heat sink temperature of 25℃。
  4. The wavelegnths of each bar in a single device can be arranged and combined according tho the heat dissipation conditions.
  5. Heat sink tructure can be customized according to customer’s special requirements.
