Abstract :
Summary form only given. Laser diodes with output powers of several watts represent key elements of modern all-solid laser technology. In this paper we present a systematic study of the emission of high-power laser arrays in a time range from 10 ns up to cw operation. We identify three different regimes of device heating in time and demonstrate strong shifts of the emission wavelength depending on the specific heat-sink configuration. The investigated double quantum well GRINSCH structure had a resonator length of 600 /spl mu/m and reflectivities of the facets 5% and 95%.
