ABSTRACT
A technique has been developed for eliminating the phase sensitivity in interferometric measurements. It is based on sawtooth phase modulation of the signal and double phase sensitive detection. It overcomes the restrictions due to background transmission that have been recognized by us in a previously proposed method based on rms detection. This paper focuses on its use in time resolved stimulated Raman gain measurements.
