We reported an actively Q-switched, intracavity Nd 3+ :YVO 4 self-Raman laser at 1176nm with low threshold and high efficiency. From the extracavity frequency doubling by use of LBO nonlinear crystal, over 3.5mW, 588nm yellow laser is achieved. The maximum Raman laser output at is 182mW with 1.8W incident pump power. The threshold is only 370mW at a pulse repetition frequency of 5kHz...
