Research on diffusion-bonding composite YVO4/Nd:GdVO4 crystal

Abstract

A 879 nm diode-laser end-pumped diffusion-bonding composite YVO4/Nd:GdVO4 crystal was firstly demonstrated at the emission of 1063 nm. Simulation results showed the temperature and stress intensity were lower in YVO4/Nd:GdVO4 crystal. A maximum continuous wave (CW) output power of 14.8 W was obtained, corresponding to the slope efficiency of 54.4% and optical-optical efficiency of 48.1%. Better laser performances are expected with the improvement of YVO4/Nd:GdVO4 crystal quality.
