Abstract
The regime of oscillation in the form of separate pulse trains with en ergy up to 4 J and controlled repetition rates from 1 to 30 Hz is stud ied. The trains consist from equidistant pulses with pulse durations f rom 50 to 100 ns and repetition rates from 500 to 900 kHz depending on the transmission of passive laser Q-switch and pump energy. Energy ef ficiency of passive laser Q-switch is equal to 0,9 with the laser osci llation efficiency beeng of 1,53% and modulation depth of 100% Beam qu ality parameter M2 is equal to 3,3, the coherence length is of 14 cm.
