Abstract: Simple analytic solutions, obtained for the energy density of the amplified radiation, are used to analyse the influence of various types of excitation of a medium on the processes of essentially transient stimulated Raman scattering and inverse Raman scattering in a powerful laser radiation field. It is shown that the excitation may alter the nature of amplification and may also reveal the initial ratio of the phases of the interacting waves.
