中文摘要	We demonstrated a 103.5 W green laser with an extra-cavity second harmonic generation. The IR source was a high power Q-switched Nd:YVO/sub 4/ MOPA laser. The type I phase-matching LiB/sub 3/O/sub 5/ was used as the nonlinear crystal in the second harmonic generation. The 103.5 W average power of 532 nm green laser was obtained at a repetition rate of 60 kHz with the beam quality factors of M/sub x//sup 2/ < 1.44 and M/sub y//sup 2/ < 1.23 in the orthogonal directions, corresponding to a peak power as high as 1.5 MW with the instability of pulse energy less than +/-4%. The optical frequency conversion efficiency from IR to green laser was up to 67%.
