## Abstract

A series of $\mathrm{Nd}:{\mathrm{Y}}_{x}{\mathrm{Gd}}_{1-x}{\mathrm{VO}}_{4}$ ($x=0.17$, 0.37, 0.53, 0.63, 0.70, 0.81) mixed laser crystals with doping concentration of $0.5\phantom{\rule{0.2em}{0ex}}\mathrm{at.}\%$ Nd were successfully grown by the Czochralski method. Thermal properties including the specific heat, thermal diffusion coefficient, and the thermal conductivity were systematically studied. The material constants ${\mathrm{M}}_{\mathrm{s}}$ were calculated and show that the thermal fracture limit of the mixed crystals should be comparable with that of $\mathrm{Nd}:{\mathrm{YVO}}_{4}$. Diode-pumped continuous-wave (CW) laser performance at $1.34\phantom{\rule{0.2em}{0ex}}\mathrm{\mu}\mathrm{m}$ and $1.06\phantom{\rule{0.2em}{0ex}}\mathrm{\mu}\mathrm{m}$ with *a*- and *c*-cut crystals was demonstrated. The influence of different *x* values on laser performance and emission cross sections was also discussed. All the results show that $\mathrm{Nd}:{\mathrm{Y}}_{x}{\mathrm{Gd}}_{1-x}{\mathrm{VO}}_{4}$ represents a new series of crystals suitable for application as high-power diode-pumped lasers.
