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(&lt；30fs)，旨在推动激光技术在峰值功率(多PW)和重复率方面的极限。建议的CDT论文将是该部门正在进行的主要开发项目的一部分。根据放置开始时的实际情况，可能的研究项目是：-开发高重复频率闪光灯泵浦的钕玻璃圆盘激光放大器；-开发反馈系统，以提高拍瓦级激光系统的指向和脉冲持续时间稳定性；-开发新型超短激光诊断；-研究用于多拍瓦光学参数放大器的非线性晶体拼接；-设计和测试大边光学参变啁啾脉冲放大激光系统；-开发模拟代码，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；-啁啾脉冲放大方案(展宽器和压缩器)的光学设计和对准，包括光束扩展和传输。

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.
