Theoretical Investigation of Electromagnetic Propagation of Ultra-Intense Radiation in Plasma

在这次美苏合作中，从理论上研究了强激光在等离子体中的传播。最重要的是研究电场比原子相互作用大的物理条件，以及相对论运动突出的物理条件。目前对这一制度的理论认识是原始的，分析所需的计算工具才刚刚开始发展。平行实验的努力将允许理论和实验的直接比较，并将导致我们对超强场中激光物质相互作用的理解取得重大进展。

The propagation of intense laser light in plasmas is studied theoretically in this US/USSR collaboration. Of paramount importance is the investigation of physical conditions in which the electric field large compared to the atomic interactions and where relativistic motions are prominent. Present theoretical understanding of this regime is primitive and the computational tools required for the analysis are just beginning to be developed. Parallel experimental efforts will allow a direct comparison of theory and experiment and should result in a significant advance in our understanding of laser-matter interactions in ultra-intense fields.
