Full-Scale Three-Dimensional Numerical Experiments on High-Intensity Laser Matter Interactions

Mori DMS- 9722121 这是一个高度多学科的建议，研究高强度激光与物质相互作用的模型。 被模拟的实验是丰富多样的现象，如相对论性自聚焦/自相位调制，拉曼散射，光子加速。 在这项工作中，我们将开发一个三维粒子细胞代码，以准确地模拟这些相互作用。 这些实验的精确建模将导致对激光与物质相互作用的新的理解。 该研究需要高强度激光等离子体物理学，激光等离子体加速，大规模粒子细胞计算机建模和大型数据集操作的专业知识。 最近，短脉冲激光技术已经发展到有大量实验结果的地方，而对正在发生的事情的理论理解却没有跟上。 在这项研究中，我们将开发准确模拟高强度短激光脉冲与物质相互作用时发生的情况的能力。 模拟这些相互作用的能力将有助于实验学家解释他们的结果，并增加我们对所涉及的物理过程的理解。

Mori DMS- 9722121 This is a highly multi-disciplinary proposal for research in modeling high intensity laser-matter interactions. The experiments being modeled are rich and varied in phenomena, such as relativistic self-focusing/self-phase modulation, Raman scattering, and photon acceleration. In this work we will develop a three-dimensional particle-in-cell code to accurately simulate these interactions. The accurate modeling of these experiments will lead to new understanding of laser-matter interactions. The research requires expertise in high-intensity laser-plasma physics, laser plasma accelerations, large scale particle-in-cell computer modeling, and manipulation of large data sets. Recently short-pulse laser technology has advanced to where there has been a great profusion of experimental results and the theoretical understanding of what is happening has not kept pace. In this research, we will develop the capability to accurately simulate what happens when a high intensity short laser pulse interacts with matter. The capability to model these interactions will help experimentalists interpret their results and increase our understanding of the physical processes involved.
