| Abstract: | 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 M2 = 1.55 and the optical frequency conversion efficiency from NIR to green laser was as high as 51%. The pulse repetition rate was tunable from 50 kHz to 200 kHz and the overall dimension of the laser was within 500 × 300 × 150 mm3. |
