An incident CO2laser beam into a low pressure SF6 cell was frequency modulated by an external dithering mirror through the Doppler effect. The differential spectrum ofSF6has been detected by utilizing the phase-sensitive technique. The frequency differencesamong several saturated absorption lines of SF6 were precisely measured. The practicalsignificance of the method is discussed.
