The effect of stimulated Raman scattering (SRS) on the propagation of a laser pulse on horizontal atmospheric paths was studied numerically in the quasioptical approximation. It is shown that SRS strongly affects the redistribution of the energy in a powerful laser pulse between the incident radiation and the Stokes component. It was found that the profile of the Stokes beam changes along the path and spreads rapidly in space. The effect of SRS increases as the wavelength of the incident radiation decreases and it becomes only insignificantly weaker on high-altitude paths (up to 20 km).
