The Central Laser Facility is devoted to developing and to providing world leading high power laser systems to the laser plasma research community.Current development programme is focused on Chirped Pulse Amplification and on ultrashort laser pulses (<30fs), aiming to pushing the limit of laser technology for the peak power (multi PW) and repetition rate.The proposed CDT thesis will be part of the major development project ongoing in the department. Possible research projects, depending of the actual situation at the start of the placement, are:- Development of high repetition rate flashlamp pumped Nd:glass disk laser amplifier;- Developing feedback systems to improve pointing and pulse duration stability of petawatt class laser system;- Development of novel ultrashort laser diagnostics;- Studying nonlinear crystal tiling for multi-petawatt optical parametric amplifier;- Design and test large side optical parametric chirped pulse amplified laser system;- Develop a simulation code aiming to study the influence of the quality of the optics and the mechanical stability on the final parameters of multi-petawatt laser systems;- Optical design and alignment of Chirped Pulse Amplification scheme (stretcher and Compressor), including beam expansion and propagation.

中央激光器设施致力于开发和为世界提供高功率激光系统到激光等离子体研究界。电流开发计划的重点是搅动的脉冲放大和超短暂的激光脉冲（<30fs），旨在推动激光的极限峰值功率技术（多PW）和重复率。拟议的CDT论文将成为该部门正在进行的主要开发项目的一部分。根据位置开始时实际情况，可能的研究项目是： - 开发高重复速率闪光灯泵送ND：玻璃磁盘激光放大器； - 开发反馈系统以改善Petawatt类激光系统的指向和脉搏持续时间稳定性； - 开发新型的超短激光诊断； - 研究多速度光学参数放大器的非线性晶体平铺； - 设计和测试大侧光学参数脉冲放大激光系统； - 开发旨在研究旨在研究旨在研究旨在研究旨在研究质量质量质量的模拟代码光学和机械稳定性在多折线激光系统的最终参数上； - chi脉脉冲放大方案（担架和压缩机）的光学设计和对齐，包括光束膨胀和传播。
