Abstract
We have studied Kerr-lens mode-locking efficiency in a Ti-sapphire las er both experimentally and theoretically. The criterion of mode-lockin g efficiency based on the spatiotemporal model of a self-consistent la ser field was proposed. We investigated ultrashort-pulse stability, ta king 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. (C) 1997 Optical Society of Amer ica.
