In this book, we focus on the stochastic nature of pulses to achieve a more realistic description of ultra-short optical pulses affected by noise. In order to simulate ultra-short pulses, various stochastic pulse models were applied. The effects of pulse amplitude and phase fluctuations on its propagation in various linear and non-linear media were studied based on optical coherence theory. The response of the medium atoms to the applied stochastic pulses was investigated for the particular resonant case in which the pulse frequency nearly coincides with the atom resonance frequency. Analytical and numerical propagation methods were applied to explore evolutions of ultra-short stochastic pulses in the vicinity of optical resonance.

\nWe discuss the possibility to control through two different experiments, the propagation effects that occur when an optically dense atomic medium is excited by ultra-short laser pulses. In the first experiment a direct compensation of the dispersion for one single pulse is obtained with a pulse-shaper device. In the second experiment, ce of ultra-short laser pulses is used. The dispersion effects are shown to depend crucially on the relative phase between the pulses.\n
