Paper Abstract

Theoretical estimates of the two-stage stimulated Raman scattering (SRS) in the atmosphere had been carried out. The first stage nonlinear parametric processes are stipulated by vibration SRS of laser beam on molecules of two (e.a., nitrogen and oxygen) gases. For considered conditions the secondary SRS can be generated by two-atomic molecules such as Cl2, F2, H2, N2. The carried out analysis of two-stage SRS had shown that it can appear in the atmosphere on distances about 1 km. The calculations show that if two-stage SRS takes place, the second stage appears very sharply. This causes very essential redistribution of energies of the secondary waves and quick exhaustion of energy of laser wave.
