ABSTRACT:
Two parallel sets of groups of beams from diode laser bars are spaced apart by a distance V. The two sets of beam groups are interleaved by a beam combiner to provide on set of beam groups spaced apart by a distance V/2. The beam combiner includes a plurality of reflective strips in a plane inclined to the direction of propagation of the beam groups. One set of beam groups is transmitted through the beam combiner without being intercepted by the reflective strips. The other set of beam groups is interleaved with the transmitted set of beam groups by reflecting the other set of beam groups from the reflective strips.
