Abstract :
Using a computer simulation, the authors have studied self-start of passive mode-locking in a laser with a nonlinear mirror in the form of a fiber loop reflector. They have demonstrated that intracavity interferometric pulse compression in a nonlinear resonator makes it possible to broaden the bandwidth and to accomplish efficient pulse shortening. Stable solutions have been found for perfect mode-locking with a steady-state pulse bandwidth which essentially exceeds the gain bandwidth.<>
