摘　　要：超强超短激光的出现与迅猛发展,为人类提供了前所未有的极端物理条件与全新实验手段,使得人类对客观世界规律的认识更加深入和系统化,显著推动基础与前沿交叉学科和战略高技术领域的创新发展。超强超短激光大科学装置对于促进人类对客观世界规律的认识以及推动前沿科学研究领域的发展具有举足轻重的作用。结合国内外超强超短激光的发展现状,介绍上海超强超短激光实验装置的研制进展,进一步展望未来的研究发展方向。Significance The rapid emergence and development of ultra-intense and ultra-fast lasers have created unprecedented physical conditions and novel experimental methods,enhancing and organizing human comprehension of natural laws while significantly advancing innovation in basic and interdisciplinary research,as well as strategic high-tech areas.Ultraintense and ultrafast laser devices have been pivotal in advancing human comprehension of fundamental laws governing the natural world and have contributed to the advancement of cutting-edge scientific research fields.In terms of ultra-intensity,using chirped pulse amplification(CPA)technology,laser systems can achieve peak powers surpassing the petawatt(PW)level,reaching up to 10 PW,with focal intensities of 1022‒1023 W/cm².This enables easy tearing of electrons and atomic nuclei by ultraintense laser fields,enabling exploration at the subatomic level of microscopic structures.For an ultrafast laser,ultrafast pulses can achieve pulse widths in the femtosecond range,enabling the measurement of femtosecond-scale physical changes.The high temporal resolution properties of lasers are crucial for investigating molecular dissociation processes,which are essential in chemical research.Additionally,the use of ultra-intense ultrafast lasers to drive nonlinear processes,such as high-harmonic generation,can produce attosecond(10-18 s)pulses,enabling the measurement of attosecond-scale electron dynamics.An article in the“Opinion”column of the January 2010 issue of Nature,titled“2020 Visions,”has analyzed the development directions of key scientific fields for the next decade and presented prospects for 2020.This study predicted five major breakthroughs that may occur in the laser field over the next 10 years,with four of them directly related to ultra-intense ultra-fast lasers.The four breakthroughs include:the precise measurement of cosmic constants using ultra-precise laser clocks;the generation of new states of matter and the provision of carbon-free and infinite cle
