We report on the output power performance and beam profile analysis of an optically pumped GaSb-based vertical-external-cavity surface-emitting laser operating at 2.25 mu m. The use of a SiC heatspreader and a precise control of the temperature-depen

In spite of elaborate heat-sinking employing intracavity heat-spreaders, the maximum output power of current (AlGaIn)(AsSb)-based vertical-external-cavity surface-emitting lasers (VECSELs) is still limited by thermal rollover (e.g., 0.8 W at 20degC a

Efficient operation of semiconductor disk lasers is demonstrated using uncooled and inexpensive 905nm high-power pulsed semiconductor pump lasers. Laser emission, with a peak power of 1.7W, is obtained from a 2.3 mu m semiconductor disk laser. This i

We report a high-power (AlGaIn)(AsSb) semiconductor disk laser emitting around 2 ?m. With a diamond heat spreader used for thermal management, a maximum output power of just over 5 W and slope efficiencies of over 25% were demonstrated. The output wa

Finite element analysis is used to study heat flow in a 2.3-mu m semiconductor disk laser (or vertical-external-cavity surface-emitting laser) based on GaInAsSb-AlGaAsSb. An intracavity diamond heatspreader is shown to significantly improve thermal m

A review on the recent developments in the field of long-wavelength (Lambda >1.2 µm) high-brightness optically-pumped semiconductor disk lasers (OPSDLs) is presented. As thermal effects have such a crucial impact on the laser performance particular
