Thermal and laser characteristics of Nd doped La₀₁₁Y₀₈₉VO₄ crystal

Abstract

A 0.3 at% Nd doped La0.11Y0.89VO4 mixed crystal was grown by the Czochralski method. The thermal properties including the thermal expansion coefficient, specific heat, thermal diffusion coefficient, and the thermal conductivity were systematically studied. Diode-pumped continuous-wave (CW) laser performance at 1.06 μm with a- and c-cut crystal were demonstrated, and the maximum output power is about 8.76 W, which is obtained at the incident power of 19.15 W. All the results show that Nd:La0.11Y0.89VO4 is an excellent crystal for application as high-power lasers. What’s more, different with the a-cut crystal, the laser spectrum of c-cut one is found to be dual-wavelength.
