We experimentally studied the temporal and spectral characteristics of the output pulses after the negatively chirped pulses passed through normally dispersive media. The spectrum of the pulse is narrowed and reshaped due to strong self-actions. The pulse is self-compressed, instead of broadening, accompanied with the spectrum narrowing in the experiment. For the same spectral bandwidth, shorter than sech2 transform-limited self-compressed femtosecond pulses are obtained. The simulation result is in agreement with the experiment.
