Abstract : Starting out from the basic principles of quantum mechanics, the dynamics equations for stimulated Raman scattering (SRS) under semi-classical theoretical conditions are obtained. Theoretical verification is done of the fact that classical descriptions are only appropriate provided the distance between upper and lower energy levels is relatively great. Numerical simulations are done of several types of effects associated with stimulated rotational Raman scattering (SRRS) when strong lasers pass through the atmosphere. In these are included influences associated with Raman rotational properties, SRRS threshold values, and molecular memory on pulse series transmission.
