Abstract
A novel technique to measure internal temperature distributions within high power semiconductor lasers with substrates transparent to the laser radiation is presented. The temperature resolution is better than 10°C with a spatial resolution of 1-2μm. The results show highly non-uniform transverse temperature distributions and significant heating close to the facet at high output powers.
