Abstract

We have experimentally investigated the combination of chirps of two ultrashort light pulses through self-diffraction induced by cascaded second-order frequency mixing in a β-barium borate crystal. Interaction of two pulses with equal carrier frequencies and opposite chirps yielded diffracted pulses with enhanced chirp. Perfect compressibility of the diffracted pulse indicates that phase distortion by intensity-dependent effects was negligible.
