940nm,100kW pulsed laser stack

High Efficiency High Power Diode Laser Source for pumping applications from Quantel Lasers. The source generates up to 100 kW power at 940 nm or 980 nm with a pulse width up to 3 ms. The components have been designed to highest possible efficiency which leads to a low power consumption, small spectral width and low heat generation. Diodes are collimated in the fast axis at a pitch of 800 μm (400 μm for 1ms pulse width). The source has 16 stacks, 10 to 20 bars each depending on the final power requested assembled with very low gap between each stack.

The 980nm laser diode source is cooled by standard water (not DI). The water circuit is physically separated from the diode housing which eliminates any risk of water leakage on stacks (included in QLD warranties). Low pressure N2 purge is necessary when water temperature is below 20°C.
