L. Chai et al., Experimental study on the self-mode-locking states in a Ti : sapphire laser using an intracavity semiconductor saturable absorber mirror, ACT PHY C E, 50(1), 2001, pp. 68-72
The self-mode-locking states in a Ti:sapphire laser using an intracavity se
miconductor saturable absorber mirror (SESAM) have been investigated experi
mentally. In this laser, three mode-locking states, i.e. the passive mode-l
ocking 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 pro
duced from the Kerr-lens mode-locking in the laser. The mode-locking mechan
ism and the role of SESAM as well as the self-starting dynamics of SESAM ha
ve been investigated and discussed.
