Claim 0:
1. A method for frequency matching a resonant cavity, comprising:
receiving light in a resonant cavity, the 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 by transmitting a signal to an actuator to vary the length of the path of the resonant cavity;
modulating the signal transmitted to the actuator to regularly oscillate the second mirror to alternatingly move towards and away from the first mirror;
monitoring 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;
determining an error correction from the monitored intensity of the light from the resonant cavity; and
actuating the second mirror, at least partially based on the error correction, towards a pose relative to the first mirror at which a frequency of the light is in resonance with the length of the path.
