This project will capitalize on improvements in laser technology that make it possible to generate extremely high laser intensities to probe in detail the highly relativistic parameter regime of laser-plasma interactions. Previous results on harmonic generation from relativistic Thomson scattering will be extended into the XUV spectral region, and the dependence of the harmonic generation on laser and plasma parameters will be explored. Previously observed ion acceleration will be studied in more detail to understand the origin of the ions and the behavior of the acceleration as a function of laser parameters. This work has technological applications to the generation of short x-ray radiation, the ignition of laser-fusion targets, and compact and inexpensive medical radiation sources.

该项目将利用激光技术的改进，使其能够产生极高的激光强度，以详细探测激光-等离子体相互作用的高度相对论性参数状态。 以前的结果谐波产生从相对论汤姆逊散射将扩展到XUV光谱区域，和谐波产生对激光和等离子体参数的依赖关系将被探索。 先前观察到的离子加速将被更详细地研究，以了解离子的起源和作为激光参数的函数的加速行为。 这项工作的技术应用，产生短的x射线辐射，激光聚变目标的点火，以及紧凑和廉价的医疗辐射源。
