Abstract: A method for adjusting an optical cavity's length includes: measuring a first absolute frequency corresponding to a cavity mode, the optical cavity having a first and second mirror having respective first and second mirror surfaces separated by a first cavity length, and a resonator body interposed therebetween; determining a length difference between the first cavity length and a target cavity length corresponding to a plurality of resonance frequencies that includes a target absolute optical frequency; removing the first mirror to expose a first end of the resonator body; depositing, on one of the first end and the first mirror, a spacer having a thickness within a length tolerance of the determined length difference; and reversibly securing the first mirror to the resonator body, the spacer being between the first mirror and the resonator body, the first and second mirrors being separated, within the length tolerance, by an adjusted cavity length.
