Abstract

The laser performances of the 1.06 μ m F 3 / 2 4 I 11 / 2 4 four-level transition and of the 0.9 μ m F 3 / 2 4 I 9 / 2 4 quasi-three-level transition were investigated using multipass pumped Nd-based media in thin-disk geometry. When pumping at 0.81 μ m into the F 5 / 2 4 level, continuous-wave laser operation was obtained with powers in excess of 10   W at 1.06 μ m , in the multiwatt region at 0.91 μ m in Nd:YVO 4 and Nd:GdVO 4 , and at 0.95 μ m in Nd:YAG. Intracavity frequency-doubled Nd:YVO 4 thin-disk lasers with output powers of 6.4   W at 532   nm and of 1.6   W at 457   nm were realized at this pumping wavelength. The pumping at 0.88 μ m , which is directed into the F 3 / 2 4 emitting level, was also employed, and Nd:YVO 4 and Nd:GdVO 4 thin-disk lasers with 9   W output power at 1.06 μ m and visible laser radiation at 0.53 μ m with output power in excess of 4 W were realized. Frequency-doubled Nd:vanadate thin-disk lasers with deep blue emission at 0.46 μ m were obtained under pumping directly into the F 3 / 2 4 emitting level.
