Abstract

In extension to known concepts of wavelength-multiplexing diode laser arrays, a new external cavity is presented. The setup simultaneously improves the beam quality of each single emitter of a standard 25 emitter broad-area stripe laser bar and spectrally superimposes the 25 beams into one. By using this external resonator in an “off-axis” arrangement, beam qualities of Mslow               2<14 and Mfast              2<3 with optical powers in excess of 10  W in cw operation are obtained.
