Spectral-phase modulation in a zero-dispersion line is a powerful method to compress or temporally shape femtosecond pulses. Results of classical spectral interferometry in characterizing and controlling phase modulators are reported. An improvement of spectral interferometry, polarization spectral interferometry, is analyzed and demonstrated for the control of polarized modulators. Possible errors and limitations are asserted. A new scheme for the real-time control of spectral phase modulation in an amplifier laser system is proposed.
