The classical theory for forward stimulated Raman scattering (FSRS) of stationary pulses is complimented by the theory of transient FSRS of rapidly amplified short laser pulses. These pulses are amplified through Raman backscattering of a long pulse, and simultaneously experiencing FSRS. FSRS suppression is analyzed by identifying quantitative conditions. It is shown that by using a selective detuning of the Stokes resonance, the limitation imposed by pumped pulse FSRS on the output laser intensity in plasma-based ultrapowerful backward Raman amplifiers can be overcome.
