摘要

An optically pumped semiconductor laser arrangement comprises a vertically emitting laser (12) having an emitter layer producing radiation, and a pumped beam source (22) for optically pumping the laser. The laser has an absorber layer for the two-photon absorption of radiation from the radiation source whose wavelength is smaller than the doubled wavelength to excite two-photon transition in the absorber layer.
