Abstract
An optoelectronic light source includes a semiconductor laser configured to produce polarized primary radiation, a converter material configured to absorb at least part of the primary radiation and convert the primary radiation into a secondary radiation of an increased wavelength, a planar multi-layered mirror located between the semiconductor laser and the converter material, the multi-layered mirror configured to transmit the primary radiation and reflect the secondary radiation, and an optical element provided between the semiconductor laser and the multi-layered mirror, wherein the optical element is configured such that the primary radiation coming from the semiconductor laser impinges on the multi-layered mirror at a Brewster angle.
