QCW Mini-Stacked Array QD-Q1S09-D(n) / QD-Q1R12-D(n) DESCRIPTION QD-Q1S09-D(n) or QD-Q1R12-D(n) are conductively cooled laser diode stacked arrays with a specific design adapted for the realization of highly compact laser diode source. These Stacks are designed to integrate reduced size diode bars allowing an emission of square shape with high optical power density: with 9 mini-bars 3mm ~3 X 3 mm² emission with 12 mini-bars 5 mm 5 X 5 mm² emission Heat-sink has been adapted for such mini-bars with a small foot-print and qualified for stable operation over large temperature range. Option is proposed with mini-bars of different wavelengths (to broaden the optical spectrum) which is well appropriate for operation under environment with non stabilized temperature. This compact stack is well adapted to be tightly packed in customerdesigned manifolds for optimized small size and efficient diode pumped solid state lasers.
