QD-Q1yzz-A, QD-Q1yzz-B, QD-Q1yzz-BS, QD-Q1yzz-G and QD-Q1yzz-K are a variety of conductively cooled laser diode stacked arrays. These Stacks can be built fr om 2 to 19 diode bars of 60W QCW to 200W QCW.

The laser diode bar arrays benefit fr om a fully mastered technology, with the appropriate design for improved efficiency and reliable operation. 

Packaging and heat-sink have been optimized to reduce the overall thermal resistance. Assembly in a compact and rugged package, using AuSn hard solder, allows easy connection to a heat exchanger to get good thermal control.

This technology of stacks has been successfully submitted to specific environmental tests requested for Space missions (long life-tests, endurance under vacuum, irradiations…).

These stacks are ideal for different applications under severe conditions: pumping rods or slabs solid state lasers, illuminators...for aerospace, industrial, space applications.
