High intensity laser plasma interactions

二十多年来，我的研究一直关注激光物质相互作用物理的理论和计算研究。该计划主要集中在三个广泛的理论和数值研究领域：(1)参数不稳定性和等离子体中的非线性激光束传播；(2)粒子输移和等离子体波动；(3)高强度超短激光脉冲等离子体相互作用。从这些核心学科衍生出来的生物医学应用和国际合作涉及第四代辐射源，包括微流控细胞术的合作研究和光离气体等离子体物理的理论研究。本研究的长期目标是提高我们对高强度激光脉冲等离子体相互作用的认识。这一知识不断受到激光新技术进步的挑战，这使得在相对论能量和天体物理相关的高度压缩状态下探索新的等离子体状态成为可能。在提出的研究计划中，我想加强我的小组在强飞秒激光脉冲及其与不同目标的相互作用相关领域的研究活动。提出的研究计划的结果将推动激光等离子体加速器的发展，相对论粒子和x射线辐射的新来源，并将有助于激光聚变计划的物理学。为这些研究提供重点的加拿大主要设施是位于蒙特利尔INRS的先进激光光源（ALLS）。

For over twenty years my research has been concerned with theoretical and computational studies of laser matter interaction physics. This program has been focused on three broad areas of theoretical and numerical investigations: (1) parametric instabilities and nonlinear laser beam propagation in plasmas, (2) particle transport and plasma fluctuations, and (3) high intensity ultra-short laser pulse plasma interaction. Spin-offs from these core subjects into biomedical applications and international collaboration involving 4th generation radiation sources have included collaborative studies in microfluidic cytometry and theoretical investigations of plasma physics of photoionized gases. The long-term goal of this research is advancement of our understanding of high intensity laser pulse plasma interactions. This knowledge has been continuously challenged by new technological advances in lasers, which enable explorations of new plasma regimes at relativistic energies and in highly compressed states of the astrophysical relevance. In the proposed research program I would like to enhance research activities of my group in areas related to intense femtosecond laser pulses and their interactions with different targets. Results of the proposed research program will advance developments of laser plasma accelerators, new sources of relativistic particles and x-ray radiation, and will contribute to physics of the laser fusion program. The main facility in Canada, which provides a focus for these studies, is the Advanced Laser Light Source (ALLS) at INRS, Montreal.
