EXPERIMENTAL STUDY ON THE SELF-MODE-LOCKING STATES IN A Ti:SAPPHIRE LASER USING AN INTRACAVITY SEMICONDUCTOR SATURABLE ABSORBER MIRROR
|
Abstract:
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.
