✦ Synopsis


A model is developed which simulates the interaction of a laser beam with a plasma. The model allows for a nonlinear dependence of the density on the amplitude of the electric field. Numerical results show that for strong nonlinearities time-harmonic fields cannot be obtained. Instead pulses of electromagnetic energy (solitary waves) are formed inside the plasma and carry energy away from the plasma.

## Abstract This paper presents the Enhanced Raman scattering of a elliptical laser beam in a collisional plasma. We have considered the mechanism of non‐uniform heating of carriers along the wave‐front, which is important in collisional plasma. The nonlinearity arising through non‐uniform heating
