Abstract

In this paper the investigation of thermal properties of the optically pumped vertical external cavity surface emitting lasers (VECSEL) is reported. The experimental technique used is thermoreflectance. The original achievements of the paper include design and construction of experimental setups allowing the measurement of the temperature distributions on the surface of the operating VECSEL with and without heatspreader. The temperature increase in case of the VECSEL with SiC heatspreader is reduced by the factor of almost 10 in comparison to the VECSEL without the heatspreader. Additionally, the lowering of the temperature of lasing VECSEL was observed experimentally.
