Abstract
In order to get a high power and solid-state UV laser, based on a plane-plane cavity, with laser diode double-end pumping Nd:YVO4 crystal, fundamental pulse at 1064nm was output under modulation of a acousto-optic Q-switch. Then the laser at 355nm was generated by the second harmonic generation and the third harmonic generation with two LBO crystals. Under the pump power of 54W, 6.67W, average output power at 355nm was obtained at 40kHz with the pulse width of 20ns and M2=1.1. The results show that the design of intra-cavity third harmonic generation lasers can give high conversion efficiency and good beam quality.
