Abstract

A high-power high-efficiency laser power transmission system at 100 m based on an optimized multi-cell GaAs converter capable of supplying 9.7 W of electricity is demonstrated. An I-V testing system integrated with a data acquisition circuit and an analysis software is designed to measure the efficiency and the I-V characteristics of the laser power converter (LPC). The dependencies of the converter's efficiency with respect to wavelength, laser intensity and temperature are analyzed. A diode laser with 793 nm of wavelength and 24 W of power is used to test the LPC and the software. The maximum efficiency of the LPC is 48.4% at an input laser power of 8 W at room temperature. When the input laser power is 24 W (laser intensity of 60000 W/m²), the efficiency is 40.4% and the output voltage is 4 V. The overall efficiency from electricity to electricity is 11.6%.
