YVO4 crystals with high optical quality were grown by Czochralski pulling method. The largest sizes were 28mm×40mm
and the weight was 126g. Using a mode-locked Nd:YAG laser with pulse width of 40ps as the pump source
we researched the Raman output properties of a YVO4 crystal in an external resonator. The total conversion efficiency for multi-wavelengths output reached 51.4%
and the largest output energy was 2.21mJ. The highest conversion efficiency for the first Stocks Raman output of 1175nm was 32%
and the largest output energy was 0.57mJ. The conversion efficiency for the second Stocks Raman output of 1325nm was 12.3%
