Influences of Compton scattering on the self-focusing of the intense laser pulse in underdense plasma
Influences of Compton scattering on the self-focusing of the intense laser pulse in underdense plasma are studied using relative theory and the model of multi-photon nonlinear Compton scattering.A new mechanism of the laser self-focusing formed by the incident laser and Compton scattered light is given out.A revised equation on the third degree electric current density is given out.The equation is simulated by using numerical numbers.The results show that the self-focusing direction of the intense laser pulse in plasma is decreased by the relative effect.The self-focusing direction is accelerated by Compton scattering.General self-focusing direction is the faster than the non-relative effect.The key cause is the frequency of the coupling light formed by the incident laser and Compton scattered light is increased than the incident laser frequency.The self-focusing direction effect taken place by the relative effect is compensated by Compton scattering effect.

期刊介绍：
The predecessor of Optical Technology was Optical Technology, which was founded in 1975. At that time, the Fifth Ministry of Machine Building entrusted the School of Optoelectronics of Beijing Institute of Technology to publish the journal, and it was officially approved by the State Administration of Press, Publication, Radio, Film and Television for external distribution. From 1975 to 1979, the magazine was named Optical Technology, a quarterly with 4 issues per year; from 1980 to the present, the magazine is named Optical Technology, a bimonthly with 6 issues per year, published on the 20th of odd months.
The publication policy is: to serve the national economic construction, implement the development of the national economy, serve production and scientific research, and implement the publication policy of "letting a hundred flowers bloom and a hundred schools of thought contend".
