Control of the spatial-temporal and polarisation properties of high power laser pulses are central to the development of compact laser-plasma-based particle accelerators and radiation sources, which have wide-ranging potential applications. Plasma can withstand extremely high energy densities and its optical properties can be varied on the ultra-fast timescale of a high power laser pulse, enabling dynamic manipulation of intense light. This project will investigate routes to controlling intense laser pulses through the use of novel solid density plasma aperture target. Recent studies have shown that the laser interaction with the dense plasma in this regime can result in range of changes to the drive laser pulse including polarisation rotation and higher order spatial mode generation. This study will make use of experiments conducted using national and international high power laser facilities and numerical studies conducted using high performance computing clusters.

控制高功率激光脉冲的时空和偏振特性是发展紧凑型激光等离子体粒子加速器和辐射源的核心，它们具有广泛的潜在应用。等离子体可以承受极高的能量密度，其光学性质可以在高功率激光脉冲的超快时间尺度上变化，从而实现对强光的动态操纵。该项目将研究通过使用新型固体密度等离子体孔径靶来控制强激光脉冲的方法。最近的研究表明，在这种情况下，激光与高密度等离子体的相互作用可以导致驱动激光脉冲的一系列变化，包括偏振、旋转和高阶空间模的产生。这项研究将利用使用国内外高功率激光设备进行的实验和使用高性能计算集群进行的数值研究。
