Abstract:
The parameters of 494–555-nm Cd(Zn)Se/ZnMgSSe green lasers with differently designed active regions pumped by a 8–30-keV electron beam are studied. The minimum threshold current density (0.6–0.8 A cm-2 at room temperature) is obtained for a structure with the active region consisting of a ZnSe quantum well with a CdSe fractional monolayer insertion.
