A GaInP-based photo-converter of laser radiation with an efficiency of 46.7% at a wavelength of 600 nm

GaInP-based laser power converters (LPC) structure grown byMOVPE and device chip design have been optimized for operation underhigh-power lasers of the green-red spectral range. Light I-V curves recordshave shown the performance of the LPC at up to 40-50 W/cm2 ofincident power densities. The highest level data were obtained for 532,600, and 633 nm power laser lines: 44.3%, 46.7%, and 40.6% under13-16 W/cm2, respectively. LPC demonstrated an efficiency of morethan 40% at the incident laser radiation power density elevated upto 40-50 W/cm2. Keywords: laser photoconverter, MOVPE, efficiency, spectral response.\
