Aperture shared laser diode array beam combiner.
An array of discrete semiconductor lasers utilizing graded-index rod lenses as collimators were fabricated to form a noncoherent laser beam combiner. Continuous wave output power of 600 mW and 5.25% total efficiency were achieved in a 5-mrad beam from a ten-diode laser array. A technique of dichroically combining five arrays is also described.
