Abstract
A passively mode-locked laser and method for generating a coherent pseudo random pulse train is disclosed. The laser comprises an optical resonant cavity that is capable of sustaining the oscillation of a plurality of resonant modes having respective phases. A saturable absorber is positioned in the resonant cavity and has an optical intensity threshold beyond which multiple mode-locked pulses with random starting times are generated in the resonant cavity and periodically emitted by the laser. A pump injects power into the resonant cavity at a level at which the optical intensity that is incident on the saturable absorber exceeds the optical intensity threshold.
