Electron-Beam and Optically Pumped ZnSe-based Lasers with Extended Asymmetrical Waveguide

Parameters of pulsed electron-beam and optically pumped lasers based on ZnCdSe/ZnMgSSe structures with a 2-μm-wide waveguide and an active region shifted towards the structure surface have been studied. It is shown that lasing occurs at the 3rd transverse mode of the optical cavity and the maximum output power could be increased essentially due to the decrease of the optical load on the laser mirrors.
