摘要：
We report for the first time a continuous wave Yb-0.06:Y0.32Gd0.62VO4 (Yb:YGdVO4) laser, based on the F-2(5/2)-F-2(7/2) transition. The free running Yb:YGdVO4 thin-disk laser oscillation takes place at many different wavelengths, covering a wide range of 1037.0-1042.2, 1028.4-1040.2, and 1021.9-1031.2 nm, for transmissions 0.5%, 1.0%, and 2.0%, respectively. As in the case of the 0.2 mm thick a-cut Yb:YGdVO4 the most efficient laser operation was achieved employing the coupler of 0.5%, producing a maximum output power of 2.25 W which gives an optical-to-optical efficiency of 21.2%, the slope efficiency being 37.3%.
