Title: Charged Plasma Particle Collision In The Presence Of A Strong Laser Field
Author: Torres-Silva H.
Sakanaka P.H.
Abstract: Starting from a quantum mechanical approach the transition probability between charged particles is transformed to inelastic cross-section. From this a simple and useful approximation is obtained for the multiphoton energy transfer processes which accompany the scattering of a charged particle. Due to the plasma potential in the presence of a strong laser field, an effective collision frequency is found. The amplitude of the electron oscillatory velocity v o in the radiation field is assumed to exceed the electron thermal velocity vte. Under these conditions, the absorption rate is independent of the initial distribution function and depends only on the photon flux intensity. The calculated effective collision frequency can be scaled as Ip, where the p-parameter is in the range of - 0.5<p≤0.5. Our results are compared with those of other formalisms and experimental results.
