Multi-wavelength direct diode lasers based on Wavelength Beam Combination for Navy applications

There is a compelling need for multi-spectral direct diode lasers for defense and commercial applications. Applications include target illumination and detection, electronic warfare, terrain/object/building mapping, construction, surveillance, industrial process control, and free-space optical communications. Existing, commercially available direct diode lasers have some of the most desirable attributes: highest efficiency, greatest compactness (small size, weight, and power or SWaP), and wavelength selectability from the ultraviolet to the long-wavelength-infrared bands. The main disadvantage is poor output beam quality. TeraDiodes technology of Wavelength Beam Combination (WBC) effectively solves the poor output beam quality problem of direct diode lasers as well as guaranteeing co-boresight over temperature of many diode laser emitters.
