Thomson scattering of EM pulses by random fluctuations in plasmas: Effect of selffocusing
Abstract
In the present paper the authors have investigated the transient Thomson scattering of the EM pulses (having Gaussian intensity distribution in space and time) from a collisional plasma with random inhomogeneities. Because of a Gaussian intensity distribution of the pulse in a plane transverse to the pulse propagation, the electrons get redistributed and affect the scattering accordingly. When the power of the pulse is greater than the critical power for selffocusing, the backscattered power is found to exhibit a maximum at a particular time, dependent on the parameters of the pulse and the plasma.
