Q-switching of Er:YAG (2.9 /spl mu/m) solid-state laser by PLZT electrooptic modulator

Small-size PLZT 8.5/65/35 ceramic modulators with the length of 4-6 mm are used to obtain Q-switched pulses of the Er:YAG lasers-the pulsewidth 150 ns, energy of the single pulse up to 5 mJ, if followed by a number of the small-intensity postlasing pulses-the total energy of pulses is up to 10 mJ.
