Petawatt (PW) femtosecond lasers are key for the realisation of high-brightness and compact radiation and particle sources for medical therapies and remote high-resolution imaging.Petawatt (PW) femtosecond lasers are key for the realisation of high-brightness and compact radiation and particle sources for medical therapies and remote high-resolution imaging.However, recent developments in the field of high energy, high repetition rate diode-pumped solid state lasers (DPSSLs) allow the replacement of flash lamps with DPSSLs, resulting in a dramatic increase in repetition rate and efficiency.STFC is now developing the Extreme Photonics Application Centre (EPAC), a new laser facility based on a 10 Hz PW titanium-sapphire amplifier pumped by a frequency-doubled DiPOLE100 system.The proposed project will focus on the optimisation of DiPOLE100 for operation in EPAC and on the investigation of laser materials and components. The candidate will be responsible for her own research activities, ranging from fundamental modelling and system design to installation and testing. In particular, the candidate will have the opportunity to work on the optimisation of DiPOLE100s frequency doubling, by implementing advanced polarisation compensation schemes and large-aperture beam shaping. The candidate will also study the impact of high energy, high average power operation on materials and components to maximise system resilience and reliability. Options for future upgrades of EPAC to 100 Hz will also be investigated as part of this project.

拍瓦（PW）飞秒激光器是实现高亮度和紧凑型辐射和粒子源的关键，用于医学治疗和远程高分辨率成像。拍瓦（PW）飞秒激光器是实现高亮度和紧凑型辐射和粒子源的关键，用于医学治疗和远程高分辨率成像。然而，近年来在高能量领域的发展，高重复率二极管泵浦固态激光器（DPSSL）允许用DPSSL代替闪光灯，从而显著提高重复率和效率。STFC现在正在开发极端光子学应用中心（EPAC），一个新的激光设施的基础上，10赫兹PW钛蓝宝石放大器泵浦的频率-将DiPOLE 100系统增加一倍。拟议项目将重点关注DiPOLE 100在EPAC中运行的优化以及激光材料和组件的研究。候选人将负责自己的研究活动，从基础建模和系统设计到安装和测试。特别是，候选人将有机会通过实施先进的偏振补偿方案和大孔径光束整形来优化DiPOLE 100 s倍频。候选人还将研究高能量，高平均功率运行对材料和组件的影响，以最大限度地提高系统的弹性和可靠性。作为该项目的一部分，还将研究将来将EPAC升级到100 Hz的备选方案。
