Time-multiplexed multi-functional coherent optical transceiver

A system comprising:

• a high-energy laser system;
• and
• an optical transceiver disposed within the high-energy laser system, the optical transceiver comprising:
• a fiber-laser transmitter configured to transmit a transmit beam toward a target;
• transmitter optics optically coupled to the fiber-laser transmitter;
• an optical receiver configured to receive a return beam;
• an adaptive active modifier optically coupled to the optical receiver;
• a local oscillator optically coupled to the optical receiver, the adaptive active modifier, and the sensor;
• and
• at least one processing device coupled to the fiber-laser transmitter and the adaptive active modifier, the at least one processing device configured to cause the optical transceiver to turn off the local oscillator during an initial time interval, emit a stream of laser pulses using the fiber-laser transmitter during the initial time interval toward the target, measure the return beam, and determine a translational velocity of the target.

A method comprising:

• initiating a first task in a first mode for an initial time interval using at least one processing device coupled to an optical transceiver, the optical transceiver comprising:
• a fiber-laser transmitter configured to transmit a transmit beam toward a target;
• transmitter optics optically coupled to the fiber-laser transmitter;
• an optical receiver configured to receive a return beam;
• an adaptive active modifier optically coupled to the optical receiver;
• and
• local oscillator optically coupled to the optical receiver and the adaptive active modifier;
• and
• initiating a second task in a second mode for a subsequent time interval using the optical transceiver.
