An interferometer Q-switch of single-mode radiation of high-power industrial lasers

摘要

An interferometer Q-switch of single-mode radiation for industrial lasers is described. It operates at a voltage of up to 1 kV and at a repetition rate of control pulses of 100 Hz to 150 kHz. Lasing modes were studied with a cw Nd : YAG laser and single-mode pulse-periodic radiation with a peak power exceeding 3kW, spatial brightness of >6 GW/cm{sup}2 sr, beam divergence of 0.5 mrad, coherence length of 52 cm, and energy efficiency of up to 0.7 was obtained.
