36.5 W high beam quality 532 nm green laser based on dual-rod AO Q-switched resonator

摘要

A high power, high beam quality, compact green laser based on dual-rod AO Q-switched resonator was designed, fabricated and tested. The laser provided a maximum 532 nm average power of 36.5 W at a repetition rate of 65 kHz with the beam quality factor of M~(2) velence 1.55 and the optical frequency conversion efficiency from NIR to green laser was as high as 51percent. The pulse repetition rate was tunable from 50 kHz to 200 kHz and the overall dimension of the laser was within 500 X 300 X 150 mm~(3).
