Pulse-periodic YAG:Nd laser emitting variable-duration (0.2–10 msec) pulses

A pulse-periodic laser operating in the free-running regime with a variable pulse duration in the range 0.2–10 msec was developed. A compact pump-lamp power supply was constructed on the basis of selection of a part of a sinusoidal power-line voltage. Experiments demonstrated the suitability of this laser in physical research on the interaction of laser radiation with various materials, in technology of processing of different materials, and in surgery.
