Room temperature pulsed operation of 498 nm laser with ZnMgSSe cladding layers

Room temperature pulsed operation of ZnCdSe/ZnSe/ZnMgSSe SCH lasers has been achieved. Blue-green stimulated emission is observed at a wavelength of 498.5 nm. The threshold current density is 2.8 kA/cm/sup 2/ for the diode made by molecular beam epitaxy.
