Abstract
We have developed and tested an integrated fiber-optic coupled diode laser array module for use as a reliable pumping source for solid-state lasers, and rugged enough to withstand the nine `gs' acceleration of a military airborne laser experiment. This compact laser module has produced 12 watts of peak power in cw and pulsed operation modes. The output beam comes from a flexible, yet hardened, fiber-optic bundle. The laser has a footprint smaller than a 3' X 5' card. It has a built-in thermo-electric cooler to provide wavelength control, and integrated cooling channels that assure continuous use. The fiber-optic output has proven itself in beam pointing and positioning applications, including end-pumping of solid-state lasers and as an airborne beacon. In the later application this compact laser was bright enough to allow continuous aircraft tracking from 200 kilometers with a beam divergence up to 10 degrees.
