Typical required power level for the VECSEL’s applications in the AMO and nuclear medicine lies in the multi-watt range. Conventional VECSELs are capable of delivering tens of watts. However, visible wavelength VECSELs suffer from a heat excess in the active region due to the pump light absorption in the DBR, which challenges achieving laser operation. The novel concept of a semiconductor membrane-external-cavity surface-emitting laser (MECSEL) is a promising solution overcoming the heat excess problem at the challenging visible wavelengths and allows further power scaling. Strategies to create gain structures for VECSELs and MECSELs aiming on direct laser emission at 750 nm will be presented.
