Injection-locked laser system

An injection-locked laser system (1, 25) comprising:

• a master laser (2) that generates a continuous-wave output field (4) having a frequency (f0);
• one or more optical modulators (5, 5a, 5d) employed to produce from the continuous-wave output field (4) a first seed optical field (6) having a first frequency (f1) and a second seed optical field (7) having a second frequency (f2);
• wherein the first seed optical field (6) provides an input to injection lock one or more optical amplifiers (8a-c) at the first frequency (f1), the one or more optical amplifiers (8a-c) producing one or more continuous-wave output fields (12a-c) for the injection-locked laser system (1, 25) at the first frequency (f1)
• and the second seed optical field (7) provides an input to injection lock one or more optical amplifiers (8d-f) at the second frequency (f2), the one or more optical amplifiers (8d-f) producing one or more continuous-wave output fields (12d-f) for the injection-locked laser system (1, 25) at the second frequency (f2);
• the injection-locked laser system (1, 25) further comprising a first phase lock control loop (27a) that provides a first feedback signal (29a) to one of the one or more optical modulators (5, 5a) to phase lock the continuous-wave output field (12a), produced at the first frequency (f1), of a first optical amplifier (8a) to the continuous-wave output field (4) and;
• the injection-locked laser system (1, 25) further comprising a second phase lock control loop (27b) that provides a second feedback signal (29b) to one of the one or more optical modulators (5, 5d) to phase lock the continuous-wave output field (12d), produced at the second frequency (f2), of a second optical amplifier (8d) to the continuous-wave output field (4).
