AI 中文摘要
在相对论自聚焦的稳态模型框架内,研究表明,在圆偏振束的传播轴上添加一层更稠密的薄等离子体,可通过逆法拉第效应使其产生的轴向磁场相比均匀等离子体情况提升10倍以上。此时轴向磁场的大小可超过激光波的磁场,这使得在辐射强度约为10^26 W/cm²(近未来有望实现)时,有望达到兆高斯级准稳态磁场水平。
英文摘要
Within the framework of a stationary model of relativistic self-focusing, it is shown that the addition of a thin layer of denser plasma on the propagation axis of a circularly polarized beam increases the axial magnetic field generated by it via the inverse Faraday effect by more than a factor of 10 compared to the case of a homogeneous plasma. The magnitude of the axial field in this case can exceed the magnetic field of the laser wave, which makes it possible, at radiation intensities $\sim 10^{26}$~W/cm$^2$ potentially achievable in the near future, to approach the level of teragauss quasi-stationary fields.
