Abstract
A theory of the backward stimulated Raman scattering of short relativi stically strong laser pulses in an underdense plasma is developed. Ana lytical study and particle-in-cell simulations show that, if the pulse excites a nonlinear wake plasma wave, a strong up- or downshift of th e backscattered radiation frequency can occur. It is shown that the st ructure of the backscatter spectrum depends strongly on the shape of t he pulse.
