Abstract: GaInP-based laser power converters (LPC) structure grown by MOVPE and device chip design have been optimized for operation under high-power lasers of the green-red spectral range. Light I–V curves records have shown the performance of the LPC at up to 40–50 W/cm$^2$ of incident power densities. The highest level data were obtained for 532, 600, and 633 nm power laser lines: 44.3%, 46.7%, and 40.6% under 13-16 W/cm$^2$, respectively. LPC demonstrated an efficiency of more than 40% at the incident laser radiation power density elevated up to 40–50 W/cm$^2$.

Keywords: laser photoconverter, MOVPE, efficiency, spectral response.
