Abstract

The propagation of strong and short laser pulses in a medium of two-level atoms is numerically investigated. The spontaneous and collisional relaxation rates are taken into account. The behavior of the pulse envelope and its Fourier transform is studied in connection with the area theorem and formation of the 2nπ-pulses. Particularly, sudden transitions from 2nπ value of the pulse area to 2(n−1)π are predicted. This effect is associated by a sudden change of the energy losses per unit distance.
