| Abstract: | LD side-pumped all-solid-state high-power Nd:YAG/KTP green laser is reported. The LD pump module at 808 nm provided by the institute of semiconductor,CAS is composed of nine 20 W laser diode arrays,which has maximum pump power of 180 W. When the φ3 mm x65 mm Nd:YAG rod is pumped,using different length of KTP crystal (type Ⅱ critical phase-matching)respectively,the highest power of 21.3 W CW green laser is obtained with 22.5 A pumping current, the power instability is better than 2% and optical-optical(1064 ～532 nm)conversion efficiency is 42.6%. |
| Keywords: | diode-side-pumped green laser Nd:YAG crystal KTP crystal intracavity frequency-doubling |
