Conduction-cooled QCW Stacked Array QD-Q1yzz-A / QD-Q1yzz-B / QD-Q1yzz-BS / QD-Q1yzz-G / QD-Q1yzz-K DESCRIPTION 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 from 1 to 19 diode bars of 60 W QCW to 400 W QCW. The laser diode bar arrays benefit from 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…) with NASA or ESA. These stacks are ideal for different applications under severe conditions: pumping rods or slabs solid-state lasers, illuminators... for aerospace, industrial, space applications.
