高功率激光应用，尤其是激光尾场加速，通过各种研究课题不断引起人们的关注，并可能带来许多基于紧凑型加速器的工业应用，从超快成像到癌症治疗。然而，实现这一目标的一个主要步骤是稳定性这一主要问题。事实上，复杂的、有畸变的激光束与等离子体的相互作用涉及许多物理现象和非线性效应，例如自聚焦和成丝。较小的激光不稳定性（即激光波前）可能会引起不同的结果，从而损害任何实际解决方案。一条有待探索的有希望的途径是使用等离子体通道来引导和校正像差光束。研究这些课题需要复杂且昂贵的实验设施。然而，快速有效地探索新解决方案的一种方法是数值模拟，尤其是粒子内细胞 (PIC) 模拟，当且仅当人们自信地实现这种像差光束时，与高斯光束相反，这种像差光束不具备解析能力。解决方案。在这项研究中，我们提出了两项​​新的进展：在 3D PIC 代码内正确实现像差激光束，与菲涅尔理论的计算相比，在真空下显示出极大的一致性）；以及通过等离子体通道内的传播来校正它们的质量。我们展示了光束方向图的改进，变得更接近单一等离子体模式，失真更小，从而表明目标应用具有更好的稳定性。通过这种针对扭曲激光束的可靠计算技术，我们现在期望进行更准确的 PIC 模拟，更接近实验条件，并通过等离子体通道获得的结果表明未来的研究前景广阔。© 2024。作者。

High-power laser applications, and especially laser wakefield acceleration, continue to draw attention through various research topics, and may bring many industrial applications based on compact accelerators, from ultrafast imaging to cancer therapy. However, one main step towards this is the arch issue of stability. Indeed, the interaction of a complex, aberrated laser beam with plasma involves a lot of physical phenomena and non-linear effects, such as self-focusing and filamentation. Different outcomes can be induced by small laser instabilities (i.e. laser wavefront), therefore harming any practical solution. One promising path to be explored is the use of a plasma channel to possibly guide and correct aberrated beams. Complex and costly experimental facilities are required to investigate such topics. However, one way to quickly and efficiently explore new solutions is numerical simulations, especially Particle-In-Cell (PIC) simulations if, and only if, one is confidently implementing such aberrated beams which, contrary to a Gaussian beam, do not have analytical solutions. In this research, we propose two new advancements: the correct implementation of aberrated laser beams inside a 3D PIC code, showing a great consistency, under vacuum, compared to the calculations with Fresnel theory); and the correction of their quality via the propagation inside a plasma channel. We demonstrate improvements in the beam pattern, becoming closer to a single plasma mode with less distortions, and thus suggesting a better stability for the targeted application. Through this confident calculation technique for distorted laser beams, we are now expecting to proceed with more accurate PIC simulations, closer to experimental conditions, and obtained results with plasma channels indicate promising future research.© 2024.
