Semiconductor laser based on a CdS/ZnSe heterostructure with longitudinal optical pumping by a laser diode

An optically pumped semiconductor laser based on a CdS/ZnSe heterostructure containing 10 coupled quantum wells is studied. The structure is grown by metalorganic vapour phase epitaxy on a GaAs substrate. A microcavity with interference dielectric mirrors is fabricated based on this structure. At room temperature under longitudinal pumping by an InGaN/GaN pulsed laser diode with a wavelength of 438 nm, the peak power of the microcavity reaches 100 mW at a wavelength of 508 nm and a pulse duration of 65 ns.
