✦ Synopsis

In this paper, we present the using of a c-cut Nd:GdVO4 as the laser media, V:YAG as a saturable absorber and LBO as nonlinear crystal to obtain the passively Q-switched intra-cavity frequency doubled red laser at 670 nm and forth harmonic generation at 335 nm UV laser. Using dual end pump configurations at total pump power of 30 W at 808 nm, the repetition ratios of 153 kHz, the pulse width of 22 ns, average output power of 82 mW, peak power of 24.4 W and single pulse energy of 0.54 μJ pulsed 335 nm UV laser are obtained, the corresponding optical to optical conversion efficiency is about 0.273%.
