Paper Abstract

We demonstrated a 50 mJ, 100 Hz, 355 nm UV laser. The third harmonic generated in a diode-pumped 200 mJ, 500 ps Nd:YAG laser system centered at 1064 nm, which based on a master oscillator power amplifier configuration. The pulse duration and temporal shape from oscillator could be modulated by an Arbitrary-Waveform-Generator and an amplitude modulator. Two LBO nonlinear crystals were employed to second and third harmonic generation respectively. The UV laser system featured an approximately flat-top temporal distribution and a 2.5% energy stability (RMS) within 1 hour.
