The preservation of carrier envelope phase (CEP) during Cross-Polarized Wave Generation (XPWG) is demonstrated through two independent experiments based on the spatially and spectrally resolved interference fringes formed by the XPW beam and its fundamental. In a first measurement, we found that the vertical fringe position on the spatial detector was maintained over many consecutive laser shots, implying practically no change in relative CEP between the XPW and the fundamental. In a second experiment, we measured the change in relative CEP between the XPW and fundamental beam by systematically varying the amount of material dispersion inside the XPW arm of the interferometer. The recorded rate of relative phase change was in excellent agreement with the theoretical value.
