Abstract
An optical locker may include an assembly. The assembly may include a beam splitter, configured to split an input beam into at least three beams; an etalon having at least three regions, positioned so that each beam passes through a different region; a detector configured to measure output intensities, Tn, of the etalon for the beam; and a controller configured to determine a ratio, Ta/Tb, of the output intensities, wherein that ratio has a slope at the output intensities which is above a threshold, obtain a target frequency of the input beam, and determine an actual frequency of the input beam based on the target frequency and the ratio of the output intensities.
