QD-Q1yzz-L2 is a conductively cooled dual laser diode stacked array designed for very compact arrangement of stacks, each with 1 to 10 diode bars. These stacks are connected in series with very tight spacing between arrays. Other configurations are available (3, 4, 5 stacks).

The laser diode bar arrays benefit from fully developed technology, designed for improved efficiency and reliable operation.

Using AuSn hard solder technology, the assembly has been optimized to reduce thermal resistance. Using Quantel Laser Diode’s proprietary hard solder technology, different diode arrays can be packaged for customer defined heat-sinks. This enables the manufacturing of compact and complex customized pumping heads.

These stacks are ideal for pumping rods or slab solid state lasers for a broad range of aerospace, defense, industrial and space application.
