摘　　要：用可饱和吸收体镜 (SESAM )的掺钛蓝宝石激光器能够稳定运转在三种不同的锁模状态 ,即可饱和吸收体被动锁模、孤子锁模加被动锁模和KLM锁模 .分析了三种自锁模的机理和SESAM的作用 .对SESAM实现KLM锁模的自启动机制进行了实验观察和讨论 .从该激光器的KLM锁模状态 ,获得了小于 18飞秒的锁模脉冲序列 .The self-mode-locking states in a Ti:sapphire laser using an intracavity semiconductor saturable absorber mirror (SESAM) have been investigated experimentally. In this laser, three mode-locking states, i.e. the passive mode-locking with a saturable absorber,the soliton mode-locking and the Kerr-lens mode-locking have been demonstrated. As short as sub-18-fs pulses were produced from the Kerr-lens mode-locking in the laser. The mode-locking mechanism and the role of SESAM as well as the self-starting dynamics of SESAM have been investigated and discussed.
