Abstract
High thermal conductivity intra-cavity crystalline heatspreaders are used to control the pump-induced temperature increase limiting the power scaling of vertical external-cavity surface-emitting lasers (VECSELs). Pump-power-limited output of greater than 0.4 W was achieved from a GaAs-based VECSEL at room temperature with the use of a silicon carbide heatspreader bonded to the surface of the gain element and 0.5 W by water-cooling the system to 7.5°C.
