Abstract

The outputs from an 11-element, linear diode laser array with broad stripes have been beam combined into a single beam with a beam quality of 20× diffraction limited in the plane of the junction. This beam combining was achieved by use of a common external cavity containing a grating, which simultaneously forces each array element to operate at a different, but controlled, wavelength and forces the beams from all the elements to overlap and propagate in the same direction. The power in the combined beam was 50% of the output from the bare laser array.
