Sub-100 Femtosecond Pulse Generation by Kerr Lens Mode-locking in Ti: Al2O3

Abstract

Ti:Al2O3 has the available bandwidth for directly generating very short tunable pulses at high average power. Passive modelocking techniques have been described in the literature [1], [2]. We report 800mW at sub-100fs (when pumped with 8W) and 2.1W output with 120fs pulsewidth (pumped with 14W).
