Abstract

While vertical external-cavity surface-emitting lasers (VECSELs) provide several superior laser properties, the heat generated by the pump laser within the active region proves to be a limiting factor for achieving higher output powers. We present our recent progress in the development of an AlGaInP-VECSEL based on a grating waveguide structure. The heat spreader is placed below the active region membrane while a grating structure is etched into the top layer of the active region. This improves the heat removal from the membrane, while the guided-mode resonances should provide good coupling of the pump and laser field as well as a high reflectivity. The VECSEL cavity is completed with an external mirror, serving also as an output coupler.
