报道了一种由全固态调Q腔内倍频激光器泵浦的宽调谐窄线宽脉冲钛宝石激光器。采用4个密集打火石玻璃棱镜作为腔内色散元件，输出波长可连续调谐至675~970 nm，光谱线宽缩短至0.5 nm。在抽运功率为23.4W，重复频率为5.5 kHz时，获得了最大输出功率为6.65W的780 nm激光，相应的转换效率为28.4%。由于钛宝石激光器的增益开关特性，输出脉冲宽度最短可达17.6 ns。
We report a widely tunable, narrow linewidth, pulsed Ti:sapphire laser pumped by an all-solid-state Q-switched intra-cavity frequency-doubled Nd:YAG laser. By using four dense flint glass prisms as intra-cavity dispersive elements, the output wavelength can be continuously tuned over 675–970 nm and the spectral linewidth is shortened to 0.5nm. The maximum output power of 6.65 W at 780nm is obtained under 23.4 W pump power with repetition rate of 5.5kHz; corresponding to an conversion efficiency of 28.4%. Due to the gain-switching characteristics of the Ti:sapphire laser, the output pulse duration is as short as 17.6 ns.
