QCW Stacked Array with ‘Fast Axis Collimation’ QD-Q1yzz-BO / QD-Q1yzz-BSO / QD-Q1yzz-BSSO DESCRIPTION QD-Q1yzz-BO, QD-Q1yzz-BSO, and QD-Q1yzz-BSSO are a variety of conductively cooled laser diode stacked arrays designed with a ‘Fast Axis Collimation’ (FAC) lens accurately fixed on each diode bar. The fast axis divergence is reduced to a very low value (8 mrad @ 1/e²). These stacks can be built from 1 to 17 diode bars with up to 400 W QCW per bar. Minimum bar pitch is 400 μm. The quality of the collimated beam is convenient for association with appropriate optical systems for applications which request very high optical beam density. The laser diode arrays benefit from a fully mastered technology, with appropriate design for improved efficiency and reliability, operating from -40°C up to 75°C. Assembly in a compact and rugged package allows easy connection which is ideal for different applications: pumping rods or slabs solid-state lasers, illuminators...
