Phase orthogonality in polarization intermodulated excitation (POLINEX) spectroscopy
This paper reports the phase orthogonality both theoreitically and experimentally in POLINEX spectroscopy with a modulated polarization and a fixed polarization of two linearly polarized optical beams. It is possible to make the phase of the Doppler-free signal orthogonal to that of the Doppler-broadened background, if the fixed polarizer is properly adjusted.
