Abstract
An overview is given of recent laboratory developments in wide-bandgap semiconductor diode lasers. We concentrate on the device science of t hese blue-green light emitters and outline some of the existing key te chnical challenges. Following a description of the current device stat us of the edge-emitting GaN- and ZnSe-based heterojunction lasers, we illustrate the special features of wide-gap semiconductor lasers by fo cusing on the physics of optical gain and possibilities in short-verti cal-cavity structures.
