对钛宝石飞秒激光器脉冲序列的强度和时间的稳定性进行了分析.实验比较了钛宝石飞秒激光器底板有无水冷的条件下,输出锁模脉冲序列的稳定性以及中心波长和光谱宽度的变化.结果表明对钛宝石飞秒激光器底板施加水冷可改善锁模脉冲的稳定性.
The stability of the intensity and time of the pulse sequence of Ti: sapphire femtosecond laser was analyzed.The stability of the output mode-locked pulse sequence and the relationship between the central wavelength and the spectral width The results show that the stability of the mode-locked pulse can be improved by applying water cooling to the Ti: Fe-based femtosecond laser substrate.
