High-efficiency electron-beam pumped green semiconductor lasers based on multiple CdSe quantum disk sheets

摘要

We report on room temperature operation of green electron beam pumped semiconductor lasers based on multiple ZnSe quantum wells with CdSe quantum disk sheets, embedded in the ZnSSe/ZnSe alternately-strained superlattice waveguide. An efficiency of 4% per facet at electron beam energies of 18-21 keV was achieved. The output pulse power up to 12 W was detected.
