Paper Abstract

We report the structure and steady-state operating characteristics of the femto-second Ti:sapphire laser. The analytical expression of saturable absorption parameter and selfphase modulation are obtained based on H.A. Haus's self- focusing model and the mode-locked equation by using the self-consistent condition. The relation between the output pulse width and these parameters, the influence of the parameter on the stability of laser are discussed separatively, and to lead some useful conclusions for the optimum design of the fs-laser and how to get as minimum pulse width as possible. By using above results, we have designed the Ti:sapphire laser that it can operate in self- mode locking while the input pump beam from argon-ion-laser is TEMoo mode about a 4 W. The pulse as short as 60 fs duration has been obtained.
