Sažetak
In this work we investigate the propagation of an ultrashort (100 fs) laser pulse in the optically thick Rb atomic vapor, in the case when the pulse duration is smaller than the inverse spectral width of the absorption line. The envelope of such a pulse experiences strong reshaping effects and develops an oscillatory temporal structure, as a result of the strong nonlinear behavior of the refractive index over the broad pulse spectrum. The pulse reshaping is investigated experimentally for different laser detunings and Rb atom concentrations. We imploy a simple theoretical model to interpret the results and demonstrate good agreement with the observations.
