| 摘 要： | 报道了LD侧面泵浦Nd∶YAG/S-KTP腔内倍频高功率660nm连续红光激光器。泵浦组件（呈三角形等间距分布）由9个20W的激光二极管组成，最大泵浦功率为180W。通过对谐振腔参数进行优化设计，用LD连续抽运3mm×65mm Nd∶YAG激光棒时，获得了波长为1319nm的基频光振荡。利用S-KTP II类临界相位匹配腔内倍频技术，当泵浦电流为22A时，获得了6.8W的连续红光激光输出，光-光转换效率为4.3％。

| Abstract: | LD side-pumped Nd∶YAG/S-KTP intracavity frequency-doubled high power CW red laser at 660nm is reported. LD pumping module is composed of nine 20W laser diodes, which has maximum pump power of 180W. The resonant cavity parameters are optimized so as to generate fundamental oscillation at 1319nm when the 3mm×65mm Nd∶YAG rod is pumped continuously. With a KTP crystal (type Ⅱ critical phase matching), 6.8W of CW red laser output and the optical-optical conversion efficiency of 4.3% are obtained when pumping current is 22A. |
