Abstract :
The authors report reliable single-pass second harmonic generation (SHG) of more than 400 mW of 532 nm average power from a compact, all-solid state non-planar ring Q-switched Nd:YAG laser. A maximum single-pass efficiency of 65% is observed. The second harmonic output is a single-frequency mode and has diffraction limited beam quality
