Dual QCW Linear Stacked Array QD-Q1yzz-L2 QD-Q1yzz-Zn DESCRIPTION QD-Q1yzz-L2 is a conductively cooled dual laser diode stacked array designed for a very compact association of stacks with up to 12 diode bars each. These stacks are biased in series, with a reduced space between them. For specific design such as 3 or 4 even more stacks in //, use the letter Z (n been the number of stacks from 2 to 25). The laser diode bar arrays benefit from a fully mastered technology, with appropriate design for improved efficiency and reliable operation. Assembly, using AuSn hard solder technology, has been optimized to reduce the overall thermal resistance. Custom assembly is also proposed to package, with our ‘full soldered’ technology, different number of stacks on the same heatsink of any proprietary design. This allows building compact and complex specific pumping heads such as V stack. These stacks are ideal for pumping rods or slab solid state lasers for a broad range of aerospace, defence, industrial and space application.
