5. FAC avalible
Vertical QCW diode laser stack Benefits:
- Customized upon request to adjust pumping structure
- Robust: Shock and vibration resistant.
- Reliable and high-quality: Ausn solder mounting. Works even under the most demanding climatic conditions.
- wavelength combination: beneficial for full temperature pumping design.
- 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:
- 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.
- VSQCW-MI/MA-100~500-N, 100~500 represent the laser power per bar can be 100w, 200w, 300w and 500w
- The above parameters are measured at the heat sink temperature of 25℃。
- The wavelegnths of each bar in a single device can be arranged and combined according tho the heat dissipation conditions.
- Heat sink tructure can be customized according to customer’s special requirements.
