1. A passively mode-locked laser, comprising:

  • an optical resonant cavity that is capable of sustaining the oscillation of a plurality of resonant modes having respective phases;

    a saturable absorber that is positioned in the resonant cavity, said saturable absorber having a threshold beyond which a pseudo random pulse train is generated; and

    a pump that injects power into the resonant cavity at a level at which the optical intensity that is incident on the saturable absorber exceeds said threshold.
