相对论性laser -等离子体相互作用自感透明区的电磁能量穿透
Electromagnetic energy penetration in the self-induced transparency regime of relativistic laser-plasma interactions
摘要：
介绍了相对论强激光辐射穿透过密等离子体的两种情形，这种等离子体可通过自感透明获得。对于超临界密度小于1.5倍的临界，激光能量的渗透发生移动到等离子体中的孤子状结构。在较高的背景密度下，激光仅在有限的长度上穿透，该长度随着入射强度而增加。在这种情况下，等离子体场结构代表交替的电子层，这些电子层被耗尽区隔开大约半个波长。
英文摘要：
Two scenarios for the penetration of relativistically intense laser radiation into an overdense plasma, accessible by self-induced transparency, are presented. For supercritical densities less than 1.5 times the critical one, penetration of laser energy occurs by soliton-like structures moving into the plasma. At higher background densities laser light penetrates over a finite length only, that increases with the incident intensity. In this regime plasma-field structures represent alternating electron layers separated by about half a wavelength by depleted regions.
