By using an improved cavitation model, relativistic self-channeling structures are derived, which make it possible to propagate laser powers exceeding the critical one for self-focusing. A propagation mode for high laser power is also presented which is qualitatively different from those in the weakly relativistic case. Structural stability analysis shows that stable self-wave-guide propagation can take place.
通过使用改进的空化模型,推导出相对论自通道结构,这使得超过自聚焦临界功率的激光功率能够传播。还提出了一种高激光功率的传播模式,它在性质上不同于弱相对论情况下的传播模式。结构稳定性分析表明可以发生稳定的自波导传播。
