钛宝石飞秒激光器的锁模机理探讨

Investigation of Ti:sapphire femtosecond laser mode-locking mechanism

测量了X型折叠腔钛宝石飞秒激光器的发光动力学曲线 ,并运用传播圆 变换圆图解分析方法 ,系统地探讨了钛宝石飞秒激光器的自锁模机理和过程 ,提出了一种新的锁模机理———自脉动克尔透镜开关放大锁模 .

In this paper, the luminescence dynamics of X-folded cavity Ti: sapphire femto-second laser has been measured, and the self-mode-locking mechanism and process of femto-second laser have been investigated systmatically by means of propagation-circle and transform-circle graphic method. A new mode-locking mechanism, self-pulsing Kerr-lens switching and magnifying mode-locking, has been put forward.
