Abstract

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