Claim 10:
11. A system for frequency matching a resonant cavity, comprising:
a resonant cavity having at least a first mirror and a second mirror defining a path along which light is reflected, one or both of the first mirror and the second mirror at least partially permitting light from the resonant cavity to pass therethrough, at least the second mirror being actuatable to vary the length of the path of the resonant cavity;
a light intensity meter configured to monitor an intensity of the light exiting or reflecting from the resonant cavity via the at least one of the first mirror and the second mirror;
a mirror actuator system configured to actuate the second mirror;
a signal generator configured to generate a signal to cause the mirror actuator system to actuate the second mirror to a pose relative to the first mirror;
a modulation generator configured to modulate the signal transmitted to the mirror actuator system to regularly oscillate the second mirror to alternatingly move towards and away from the first mirror; and
a logic unit configured to determine an error correction from the intensity of the light monitored by the light intensity meter,
wherein the signal generator is configured to modify the signal sent to the mirror actuator system, at least partially based on the error correction, to actuate the second mirror towards a pose relative to the first mirror at which a frequency of the light is in resonance with the length of the path.
