LD-pumped Nd：AG/KTP intra-cavity double frequency 16W CW green laser

DAI Hou-mei; BAI Jin-tao

In order to get high power CW green output,the laser pumped by 9×20W high power laser diode arrays with a type Ⅱ phase matched KTP crystal was developed.Properly enlarging the light waist where KTP crystal was laid to avoid "gray tracks effect".At last,16W CW green laser output and 40% second-harmonic genration conversion efficiency were achieved at pumping current of 19.5A,with compensating phase mismatch by angle departure.The results show that Nd:YAG/KTP are good choice for high power CW green output.
