摘要：
A model of the laser pulse propagation through a medium with a special mechanism of optical limiting - the effect of the reverse saturated absorption - was proposed. It is shown that the propagation through three-level medium with reverse saturable absorption leads to decrease duration and transformation of the profile of the pulse. Analytical expressions for the maximum intensity shift and change of duration of the laser pulse were obtained.
