A diode-pumped efficient 2.05-mum Tm,Ho:GdVO(4) laser with high beam quality is reported. The cavity configuration was optimized for weakening influence of thermal effect to resonator stability and mode-coupling. A conversion efficiency of 46% and a slope efficiency of 50% were obtained with continuous-wave (CW) output power of 10.5 W at 77 K. A repetitively Q-switched laser also achieved 10.1 W of output power at 10 kHz. A beam quality factor of M(2) < 1.1 was measured by the traveling knife-edge method. In addition, the energy per pulse of 1.9 mJ was obtained at 5 kHz, corresponding to the peak power of 0.14 MW.
