摘要
A diode pumped laser wherein third harmonic generation at 355 nm is obtained from an intra-cavity-tripled diode-pumped Nd:YVO4 crystal utilizing an angle-tuned LBO doubler and tripler, and operated at high repetition rates and good overall efficiency. An average UV power of over 2 watts at 30 kHz and 1 watt at 100 kHz is typically obtained with a 20 watt diode array "bar" side-pumping a one percent (1%) Nd:YVO4 (vanadate) slab. The device utilizes room temperature intra-cavity doubling and takes advantage of a small beam waist at the doubler and tripler required with low-power CW diode pumping.
