Abstract

A diode-pumped $\mathrm{Tm},\mathrm{Ho}:{\mathrm{GdVO}}_4$ laser with a side-pumping configuration is demonstrated for the first time to our knowledge. Optimum Tm and Ho dopant concentrations for ${\mathrm{GdVO}}_4$ are somewhat lower than those for garnet and fluoride crystals. With a 3% $\mathrm{Tm}, 0.3\% \mathrm{Ho}:{\mathrm{GdVO}}_4$ crystal an output energy of 31.2 mJ and a slope efficiency of 14.5% were obtained in normal-mode operation at room temperature.
