Self-starting mode-locked laser with a nonlinear ring resonator

Abstract
A laser with a ring resonator that incorporates a nonlinear antiresonant loop is proposed and analyzed. With computer simulation it is shown that the mode-locking process is self-starting and that, when the laser is properly designed, gain-bandwidth-limited pulses can be obtained. Passive mode-locked, bistable, and chaotic solutions are found to depend on the design parameters of the model.
