Abstract :
A violet-green integrated laser converter with a quantum efficiency up to 25.4% and maximum output pulse power of 154%mW at a wavelength of 543%nm has been fabricated on the basis of the II-VI laser heterostructure comprising an active region with five electronically-coupled CdSe/ZnSe quantum dot sheets embedded in a Zn(Mg)SSe/ZnSe superlattice graded-index waveguide. A pulse InGaN/GaN laser diode emitting at 416%nm was used as a pumping source of the laser converter.
