Abstract
Different aspects of thermal management of GaAs-based verticalexternal-cavity surface-emitting lasers (VECSELs) are described and analyzed by example of typical configurations of GaInNAs/GaAs multiple-quantum-well (MQW) VECSEL. Simulations of twodimensional heat-flux spreading within investigated structures have been carried out with the aid of the self-consistent thermal finiteelement method. Influence of pumping-beam and heat spreader properties on maximal temperature increase have been studied and different heat management techniques have been compared.
