Abstract:High energy picosecond pulse trains from a passively mode-locked Nd: YAG laser are obtained. The negative feedback controlled oscillator delivers 10–30 mgrs trains with energies of up to 30 mJ and single pulse duration of less than 25 ps. The laser is operated with a repetition rate of 10 Hz. An active Q-control of the cavity generates a short pulse train with duration of 30–40 ns. The long pulse train energy reproducibility is better than ± 1.5%.
