Both solids and liquids when illuminated with an intense ultrashort laser pulse will emit XUV light, with attoseconds duration. This PhD will investigate methods to generate attosecond and extreme UV, (XUV), pulses from different types of materials, with the dual aims of understanding how extreme UV light is produced in these materials and developing XUV photonic devices. This work is part of an emerging new branch of strong field physics, with the potential for a solid-state based, compact source of attosecond pulses. In particular this PhD will investigate the time dependence of extreme electron dynamics in solids and liquids. The strongly driven electrons created in HHG emission generate petahertz rate currents within the bands and these can be exploited to write information onto coherent electron wave emission and develop petahertz opto-electronics.

固体和液体在被强烈的超短激光脉冲照射时都会发出持续时间为阿秒的XUV光。该博士将研究从不同类型的材料中产生阿秒和极紫外（XUV）脉冲的方法，其双重目标是了解这些材料中如何产生极紫外光并开发XUV光子器件。这项工作是一个新兴的强场物理学的新分支的一部分，与固态为基础的，紧凑的阿秒脉冲源的潜力。特别是这个博士将调查极端的固体和液体中的电子动力学的时间依赖性。在HHG发射中产生的强驱动电子在频带内产生Petahertz速率电流，并且这些可以被利用来将信息写入到相干电子波发射上并开发Petahertz光电子学。
