Abstract : A pulsed laser includes a polarization section having a port, the polarization section being for receiving light at the port in a selected state of polarization and for outputting light at the port having a state of polarization orthogonal to the selected state of polarization. The laser also includes an amplifying section having a port, a bidirectional amplifier, and a rotator-reflector, the amplifying section being for receiving light at the amplifying section port and for outputting light at the amplifying section port amplified with respect thereto, the bidirectional amplifier being operatively coupled to the amplifying section port at a first end and operatively coupled to the rotator-reflector at a second end. The pulsed laser further includes means for transmitting light in both directions between the polarization section port and the amplifying section port, an amplitude modulator responsive to a modulation signal for actively mode-locking light internal to the pulsed laser, and means responsive to light internal to the polarization section for outputting coherent light.
