Abstract: A unique method and apparatus for the determination of the wavelength of a laser output in a multi- or stepped-etalon laser wavelength stabilization system i s disclosed. Determination of the laser frequency is based on signals from each etalon pa th in the system, thereby compensating for subsequent changes in the optical characteristics of the etalons caused by varying temperatures. A corrective offset for the measured frequency of the laser output is determined based on values measured by each etalon and values previously stored in a look-up table. The frequency measurement is then adjusted by the determined offset to provide a more accurate determination of the laser frequency.
