Öffentlicher Vortrag: Mode-locking without saturable absorber Public lecture: Mode-locking without saturable absorber

Mode-locking is the key technology for generation of femtosecond andattosecond pulses, which are the shortest controllable events in nature. On the theory side, it isgenerally agreed that one cannot mode-lock a laser without an effective saturable absorber. In the past decade, however, there have been numerous reports that seem to defy this paradigm. Der Vortrag findet in englischer Sprache statt.
