Abstract
The interaction of ultrashort pulses and their bound states in fiber lasers with a saturable absorber are analyzed by numerical simulation. It is shown that the distance between two interacting pulses in the lasing mode established after a transient process can take a set of quantized values in which neighboring pulse separations correspond to steady bound states of opposite parity. Characteristic changes in the established states with a change in the parameters of the laser system are demonstrated. The developed model of passive laser mode locking and the results presented in the paper can be used to describe and interpret the lasing modes of fiber lasers with nonlinear losses due to different nanomaterials (media with quanta wells, nanotubes, graphene, etc.).
