Abstract:In this study the nonlinear dependences of simultaneous ponderomotive-relativistic self-focusing on the ripple characteristics including the initial width of the ripple, the phase difference between the electric fields of the main beam and the ripple, the amplitude of electric field, and the position of the ripple on the wave front of the beam are found. The intensity profile of the main beam is regarded as Gaussian profile and the ripple is assumed as ring ripple. All the results are verified by solving for t… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
