摘　　要：报道了LD侧面泵浦Nd∶YAG/S-KTP腔内倍频高功率660 nm连续红光激光器。泵浦组件(呈三角形等间距分布)由9个20 W的激光二极管组成,最大泵浦功率为180 W。通过对谐振腔参数进行优化设计,用LD连续抽运3 mm×65 mm Nd∶YAG激光棒时,获得了波长为1 319 nm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22 A时,获得了6.8 W的连续红光激光输出,光-光转换效率为4.3%。LD side-pumped Nd ： YAG/S-KTP intracavity frequency-doubled high power CW red laser at 660 nm is reported. LD pumping module is composed of nine 20 W laser diodes, which has maximum pump power of 180 W. The resonant cavity parameters are optimized so as to generate fundamental oscillation at 1 319 nm when the 3 mm × 65 mm Nd ： YAG rod is pumped continuously. With a KTP crystal （type Ⅱ critical phase-matching）, 6.8 W of CW red laser output and the optical-optical conversion efficiency of 4. 3% are obtained when pumping current is 22 A.
