摘　　要：高功率激光装置是一个复杂的有源巨型光学工程,其性能指标要求逼近科学技术与物理极限。驱动器研制有物理设计、工程光学和结构工程设计三大过程,工程光学在其中起着重要作用。高功率激光装置工程光学设计需遵循其特有的设计原则和要点,以保证装置的高性能。根据驱动器设计指标和设计特点,从总体光学设计、光束质量控制以及光束打靶精度控制方面,综述了高功率激光装置工程光学设计中的关键科学技术问题以及相应解决方法,为未来高功率激光驱动器的发展提供必要的工程设计参考。Significance The high-power laser facility(HPLF)is the most sophisticated active optical system,whose performance is required to approach the physical limits.There are three primary procedures in designing HPLFs for research on inertial confinement fusion(ICF),namely,physical design,optical design,and mechanical design,in which optical engineering plays an important role.Optical engineering of HPLFs needs to follow its specific design principles and key points to achieve high output energy and precision beam quality.Given the final goal and feature of the laser facility,this paper describes the crucial technical issues in optical engineering development and their corresponding solutions from the aspects of the techniques for beam quality control,system alignment,target positioning,and associated technologies.Progress The high-power neodymium glass laser driver is internationally recognized as the most mature laser driver for physical research on ICF.It is also an indispensable and important platform for studies of high-energy-density physics and extreme-condition physics problems,as well as basic research on astrophysics.As one of the most representative giant optical projects in the world,the laser driver integrates advanced optics,laser technology,precision machinery,and computer control.Its scale and overall performance represent a country's highest level of laser technology and engineering.Many great powers of science and technology all over the world have carried out research on laser fusion and implemented the development plans of laser drivers,and several generations of HPLFs have been successively developed and built.The United States built the world's largest experimental device for laser fusion,i.e.,the National Ignition Facility(NIF),in 2009.France is building a large-scale laser nuclear fusion device LMJ,which is similar to the NIF,and 56 laser beams in it have been operating at full power since 2019.Japan,the United Kingdom,and Russia have also built or are building smaller laser fusion devices.At th
