英文摘要	An apparatus (33) comprising a first reference element (71) having an output power that varies monotonically with input frequency over an operating frequency range and receiving at least a portion of an output beam of light from an optical source (24). A second reference element (72) having an output power that is frequency dependent receives at least a portion of the output beam of light. A first optical detector (82) measures the power of a first reference beam of light from the first reference element. A second optical detector (97) measures the power of a second reference beam of light from the second reference element. Electronic circuitry (73) is coupled to the first and second optical detectors for receiving first and second reference signals therefrom and producing a coarse error signal for permitting coarse adjustment and a fine error signal for permitting fine adjustment of the frequency of the output beam of light.
