Technological development in Multi Petawatt laser system

中央激光中心致力于为激光等离子体研究界开发和提供世界领先的高功率激光系统。目前的开发计划集中在啁啾脉冲放大和超短激光脉冲（<30 fs），旨在推动激光技术的极限，（多PW）和重复率。拟议的CDT论文将是该部门正在进行的主要发展项目的一部分。可能的研究项目，根据实际情况，在开始的位置，是：-高重复率闪光灯泵浦的钕玻璃盘激光放大器的发展;-发展反馈系统，以提高指向和脉冲宽度的稳定性的拍瓦级激光系统;-发展新的超短激光诊断;-研究非线性晶体拼接的多拍瓦光学参量放大器;- 设计和测试大侧面光学参量啁啾脉冲放大激光系统;-开发旨在研究光学质量和机械稳定性对多拍瓦激光系统最终参数的影响的模拟代码;- 啁啾脉冲放大方案（展宽器和压缩器）的光学设计和对准，包括光束扩展和传播。

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.
