摘　　要：本工作中采用四镜折叠像散腔有效地补偿像散,用复合双折射晶片调谐波长,在约10W的氩离子蓝绿激光泵浦下。TEM_(oo)模连续Ti:Al_2O_3激光峰值功率(波长λ=790nm)大于1.65W,泵浦阈值低于1.7W,斜效率为20.26％;波长λ=790nm处,输出激光线宽约为0.0008nm,含三个纵模。用一套腔镜得到的波长调谐范围约为750～869nm。Tunable CW Ti : Al_2O_3 laser with four-mirror folded cavity compensating the astigmation of the Brewster—angle Ti : Al_2O_3 rod and with complex birefringent filter tuning the wave—length was demonstrated. 1.65W CW TEM_(00)-mode output (λ=790nm) , 1.7 W pump threshold and 20.26% slope efficiency were obtained pumped by 10W visible all lines argon laser, The linewidth of output laser is about 0.0008nm with three longitudinal modes at λ=790nm. The tuning range is from 750nm to 860nm with a set of cavity mirrors,
