研究表明,不用碰撞脉冲锁模技术,而由一台简单的线型腔染料激光器,就可成功地产生短达38飞秒的光脉冲。这种激光器用六镜折叠腔,其中有Rh6G和DOPCI两个喷流和一个棱镜对色散补偿器,用连续锁模Nd:YAG激光器的倍频输出同步泵浦。染料激光脉冲的平均功率为20mW,脉冲重复频率近100 MHz。

We have demonstrated that optical pulses as short as 38fs can be successfully generated from a simple linear-cavity dye laser. The laser consists of a six-mirror cavity with two dye jets (a gain jet with Rh 6G and a saturable absorber jet with DODCI) and a pair of prism as group-velocity disperesion compensator, and is synchronously pumped by the frequency-doubled output of a CW mode-locked Nd: YAG laser. The average output power is 20 mW at a reptition rate of 100 MHz.
