摘要:

1985年,Donna Strickland和Gérard Mourou等提出了啁啾脉冲放大(chirped pulse amplification,CPA)技术的概念,这是超高峰值功率超短脉冲激光技术发展的一个重要里程碑,直接推动了超强超短激光和强场激光物理等研究领域的诞生。目前,利用CPA技术已经可以获得峰值功率达到10拍瓦(PW,1 PW =1015 W)量级的激光脉冲,被认为是“将影响从聚变到天体物理的每一项研究”的成果。也正因此,发明啁啾脉冲放大(CPA)技术的法国科学家Gérard Mourou和加拿大科学家Donna Strickland,获得了2018年诺贝尔物理学奖。首先,初步介绍了Strickland和Mourou提出的啁啾脉冲放大(CPA)技术;然后,结合上海光学精密机械研究所强场激光物理国家重点室在超强超短激光技术和强场激光物理研究等方面的成果,以及承担的国家重大科技基础设施项目“上海超强超短激光实验装置”,简单介绍了Gérard Mourou和Donna Strickland 获奖的意义;最后,对相关领域未来发展进行了初步的展望。

Abstract:

In 1985, Donna Strickland and Gérard Mourou published a paper about the invention of chirped pulse amplification (CPA) conception, a milestone of high peak power laser development, which generated the ultra-intense and ultra-short laser and high field laser physics. Now, the peak power of PW even 10 PW is possible based on CPA, which is regarded as “their work will affect research on everything from fusion to astrophysics”. Therefore, due to the invention of CPA, Prof. Gérard Mourou and Prof. Donna Strickland won the Nobel Prize in Physics 2018. This paper will give a brief introduction about the CPA technology, and the significance about Prof. Gérard Mourou and Prof. Donna Strickland’s invention with the recent progresses of ultra-intense and ultra-short laser, related high field physics and Shanghai Superintense Ultrafast Laser Facility (SULF) in State Key Laboratory of High Field Laser Physics in SIOM.
