A high power, quasi-continuous wave ultraviolet laser at 355nm was obtained by intracavity frequency tripling of a diode side-pumped acousto-optic (AO) Q-switched Nd:YAG laser. Type II critical phase-matched KTP and LBO crystals were used for the second harmonic generation and the third harmonic generation, respectively. Under the pump power of 180W, 7.8W average output power at 355nm was obtained at 8kHz with the pulse width of 50ns, corresponding to the pump-to-ultraviolet conversion efficiency of 4.3%. The peak power and single pulse energies were estimated to be 18.8kW and 938μJ. Its far-field divergence was measured to be about 2.1mrad. The instability...
