Abstract
We introduced a wavelet-transform technique into the carrier-envelope phase extraction from the spectral interferogram of amplified ultrashort optical pulses. With this technique, carrier-envelope phases were directly extracted from the ridges of the wavelet transforms. This technique did not need filters; therefore, the uncertainty introduced from filter was avoided naturally. The Wavelet transforms technique produced a two-dimensional topography on which the time-frequency information of the spectral interferogram was shown apparently.
