Abstract

Self-consistent thermal model of semiconductor disk lasers is presented. The model was used to study thermal properties of the GaAs-based InGaAs/GaAs quantum-well disk laser emitting the 980-nm radiation and equipped with a heat spreader. For a proper laser thermal management, the 300-µm CVD heat spreader has been found to be optimal, an optimal diameter of the pumping spot is equal to about 200 µm and optimal radii of the laser copper heat sink and the laser crystal are equal to about 7.5 mm and 2.5 mm, respectively..
