Abstract
The development of ultrashort-pulse oscillators by using Kerr-lens mode locking (KLM) has allowed the generation of pulses as short as 10 fs with pulse energies of a few nanojoules. To increase the available pulse energy by an order of magnitude without the use of separate amplification systems, cavity dumping of pulses can be used,1,2 Cavity dumping exploits an ultrafast Bragg diffraction cell to switch out a single pulse from the oscillator with high efficiency. Because this represents a large perturbation to the KLM process, the investigation of the recovery of the oscillator immediately after the switchout gives a good example of a solitonlike evolution out of equilibrium. This can yield insight into the physics of the oscillator itself.
