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.
