A GalnP-Based Photo-Converter of Laser Radiation with an Efficiency of 46.7% at a Wavelength of 600 nm

GalnP-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 .
