摘要：

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-mu m CVD heat spreader has been found to be optimal, an optimal diameter of the pumping spot is equal to about 200 mu m 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.
