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.}, language = {en} } @article{RaabPostnov1997, author = {Raab, Volker and Postnov, D.}, title = {Induced hysteresis-free transitions in a bistable system (experimental verification)}, year = {1997}, language = {en} } @article{RaabUllnerMenzel2000, author = {Raab, Volker and Ullner, Ekkehard and Menzel, Ralf}, title = {Novel External Resonators for High Power Diode Lasers with Improved Beam Quality}, year = {2000}, language = {en} } @article{RaabMenzel2002, author = {Raab, Volker and Menzel, Ralf}, title = {Phase-locked array of 25 broad-area lasers}, isbn = {0-8194-4368-9}, year = {2002}, language = {en} } @article{HeuerSchultheissHodgsonetal.1999, author = {Heuer, Axel and Schultheiss, J. and Hodgson, N. and Kurths, J{\"u}rgen and Menzel, Ralf and Raab, Volker}, title = {Transverse effects in phase conjugate laser mirrors based on stimulated brillouin scattering}, year = {1999}, language = {en} } @article{RaabSkoczowskyMenzel2003, author = {Raab, Volker and Skoczowsky, Danilo and Menzel, Ralf}, title = {Tuning high-power diodes with as much as 0.38 W of power and M2 = 1.2 over a range of 32 nm with 3-GHz bandwidth}, year = {2003}, language = {en} }
