Abstract
The system and method for modifying the output beam parameters of a plurality of laser diode array sources comprises scalable pump sources for use with diode pumped alkali lasers. The present invention optimizes a diode laser pump source by spectrally-narrowing stacks of diode laser array bars using a single external cavity outfitted with a proprietary step-mirror and cylindrical optical elements. The system and method of the present invention multiplies by one-hundred fold the number of stacks that can be narrowed, vastly increasing the attainable power output by utilizing beam-splitters.
