Title: Spectral Features of the Interaction of Femtosecond Light Pulses of Different Frequencies near the Boundary of a Kerr Medium

Abstract

The interaction of probe ultraviolet (UV) and intense infrared (IR) pump pulses with a duration of 150 fs in a thin 2-mm-long sample of fused silica has been studied theoretically and experimentally. The spectra of UV radiation at the output of the sample have been measured depending on the time delay between the pulses at the sample input. The maximum shifts of the spectrum, attaining up to 0.22 nm for an IR power density of 3 x 10{sup 11} W/cm{sup 2}, have been observed under conditions of coincidence of the pulses at the sample input and output, which corresponds to a predominant interaction of the probe radiation with the leading and trailing edges of the pump pulse near the boundary of the medium. The observed dependences are interpreted as a manifestation of the cross-phase modulation due to the Kerr nonlinearity of the medium and the dispersion of the group velocities of the UV and IR pulses. The numerical simulations performed taking into account these effects agree well with the experimental data.
