All-optical streaking in a cubic nonlinear medium is analyzed theoretically. The model based on the variational method employs the induced phase front distortions on a probe beam. The numerical calculations for a planar inert-gas filled waveguide show that on-line measurements of picosecond pulse durations in the short-wavelength region are possible.
