摘　　要：强激光领域目前正处于取得重大突破和开拓应用的关键阶段,尤其以面向高峰值功率的超强超短激光和高平均功率的高能连续激光为代表。近五年来,国内外基于啁啾脉冲放大及其衍生技术的超强超短激光大科学装置已经突破十拍瓦量级峰值功率,数百千瓦平均功率高能光谱合束连续激光装备已交付使用,其中反射式全息平面衍射光栅作为当前强激光技术发展的关重件,中国科学院上海光学精密机械研究所在最大口径脉冲压缩光栅和高性能合束光栅研制方面领先国际;未来五年,国际范围内百拍瓦超强超短激光装置建设任务将陆续上线、高能连续激光也将一举迈向新台阶,由此拉动千亿级行业的发展,其中高性能衍射光栅的支撑和功率引领作用不可替代。综述了强激光与反射式全息平面衍射光栅的交织发展,重点介绍国内外金属型和全介质型光栅的研究进展,并展望了追逐新时代强激光之旅中光栅领域面临的新任务及其挑战。Significance The field of high-power lasers is at a critical stage of making major breakthroughs and developing applications,especially for high-peak power,ultra-intense,ultrashort lasers and high-energy continuous lasers with high average power.Over the past five years,ultra-intense,ultra-short laser facilities based on chirped pulse amplification and their derivative technologies have broken through 10 petawatts(PW)of peak power,and spectral beams combining continuous-wave laser equipment with hundreds of kilowatts of average power have been delivered.Reflective holographic surface-relief diffraction gratings are the core components of current high-power lasers.The Shanghai Institute of Optics and Fine Mechanics(SIOM)develops the meter-scale(1620 mm×1070 mm)pulse compression grating(PCG)and the advanced spectral beam combining grating(SBCG)worldwide.In the next five years,global development works for the delivery of 100 PW lasers will be online.In addition,the output power of high-energy continuous lasers will also enter a new stage.Accordingly,the high-power laser will necessitate the development of billion dollar industries.Advanced diffraction gratings will play an important supportive role in contributing to the power growth of high-power lasers.Currently,both domestically and abroad,the field of high-power laser diffraction grating exists in both a growth period and a stable period.Therefore,it is necessary to review and look forward to the research trends in the field of high-power laser diffraction gratings from the perspective of those who have experienced the development of the field in China and are oriented to the real needs and real problems.This paper is dedicated to the 60th anniversary of SIOM and takes this opportunity to salute all those who have participated in and contributed to high-power laser grating in China.Progress In this study,the domestic and international research progress of PCG and SBCG over the past 40 years has been reviewed based on the demand(Fig.2)for reflective holographic
