The results of numerical simulation of femtosecond laser pulse propagation in main atmospheric gases (N2 and O2) under the effects of coherent Raman scattering are considered. It is shown that when femtosecond 2p-pulses propagate through a gaseous medium, SRS regime is implementable, under which energy losses are insignificant.
