1. A semiconductor laser, comprising:

  • a traveling wave laser cavity;

    an active section coupled to a waveguide, the active section comprising a forward biased laser gain medium region and a saturatable absorber comprising a reverse biased laser gain medium region;

    wherein the forward biased laser gain medium region is between 5 and 20 times longer than the reverse biased laser gain medium region;

    a laser output from the active section coupled to the waveguide;

    a pulse stretcher embedded m the traveling wave laser cavity; and

    a pulse compressor embedded in the traveling wave laser cavity;

    wherein, the traveling, wave laser cavity has a direction of propagation the pulse stretcher is coupled to the waveguide after the laser output and before the active section, in the direction of propagation; and

    the pulse compressor is coupled to the waveguide after the active section and before the laser output, in the direction of propagation.
