Abstract
We have studied Kerr-lens mode-locking efficiency in a Ti-sapphire laser both experimentally and theoretically. The criterion of mode-locking efficiency based on the spatiotemporal model of a self-consistent laser field was proposed. We investigated ultrashort-pulse stability, taking into account the gain saturation and group-velocity dispersion. A stable regime of double pulse collision at the active medium has been observed and analyzed theoretically.
