TY - JOUR A1 - Jechow, Andreas A1 - Raab, Volker A1 - Menzel, Ralf T1 - High cw power using an external cavity for spectral beam combining of diode laser-bar emission N2 - 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 M-slow(2) < 14 and M-fast(2) < 3 with optical powers in excess of 10 W in cw operation are obtained.
