非线性等离子体中的光学多重散射与“无赖波”

Optical Multi-hysteresises and "Rogue Waves" in Nonlinear Plasma

A. E. Kaplan

摘要:

由于自由电子的相对论质量效应,在强光照射下,过密等离子体层会表现出显著的非线性光学效应:反射和跃迁的多重散射,以及出现巨大的“流氓波”。这些是被困在层内的准孤立子场尖峰,一旦它们被更大数量级的泵浦激发,它们就被入射辐射维持,其峰值强度只有一小部分。这种现象甚至在具有“软”边界的层中以及在具有低吸收的半无限等离子体中也持续存在。

英文摘要:

An overdense plasma layer irradiated by an intense light can exhibit dramatic nonlinear-optical effects due to a relativistic mass-effect of free electrons: highly-multiple hysteresises of reflection and transition, and emergence of gigantic "rogue waves". Those are trapped quasi-soliton field spikes inside the layer, sustained by an incident radiation with a tiny fraction of their peak intensity once they have been excited by orders of magnitude larger pumping. The phenomenon persists even in the layers with "soft" boundaries, as well as in a semi-infinite plasma with low absorption.
