title: Spectrum reshaping and pulse self-compression in normally dispersive media with negatively chirped femtosecond pulses.
abstract: The spectral and the temporal behavior of high-intensity negatively chirped femtosecond pulses in normally dispersive media at different input parameters are experimentally studied. The spectrum of the pulse is reshaped due to strong self-actions. The pulse is self-compressed, instead of broadening, accompanied with the spectral FWHM bandwidth shortened. Steepening of the leading edge of the pulse and spectral red-shift are observed in the experiment. The numerical simulation shows that the result is in agreement with the experimental result.
