在过去的几年里，我们目睹了激光技术的飞速发展。激光强度I每隔几年就增加两个数量级，现在在拍瓦激光器发射的辐射中已经达到I × 1021 W cm-2的值[1]。这些脉冲的电场是1012 V cm-1的顺序，大大超过了原子间的领域。如此大的电场完全电离了与之相互作用的物质，并可以迫使等离子体中的电子以相对论能量振荡。在这些区域中，无碰撞等离子体的非线性动力学特性及其与电磁波的相互作用成为非常重要和有吸引力的理论研究。
Over the last few years we have witnessed extremely rapid progress in laser technology. The laser intensity I has increased by two orders of magnitude every couple of years and has now reached a value of I ≈ 1021 W cm-2 in the radiation emitted by petawatt lasers [1]. The electric field of these pulses is of the order of 1012 V cm-1, significantly exceeding the interatomic field. Such a large electric field fully ionizes the matter with which it interacts and can force the electrons in the plasma to oscillate with relativistic energy. In these regimes the specific features of the nonlinear dynamics of collisionless plasmas and their interaction with electromagnetic waves become very important and attractive for theoretical studies.
