啁啾脉冲放大技术——从超快激光技术到超强物理世界

Chirped pulse amplification——from ultrafast laser technology to ultraintense physics

2018年的诺贝尔奖揭晓,3位科学家因在光学技术领域作出的开创性发明而获得物理学奖。其中Arthur Ashkin教授因为发明光镊技术(Optical Tweezer)分享了一半的奖金;Gérard Mourou教授和Donna Strickland副教授因共同发明啁啾脉冲放大技术(Chirped Pulse Amplification,CPA)分享了另一半奖金。作为突破高强度激光发展瓶颈的重大技术创新,CPA技术自发明以来一直是激光物理研究、特别是超快激光研究的核心技术。文章将主要简述该技术发明的相关背景、原理、结构及所导致的激光进展和开拓的超强物理应用。

The Nobel Prize in 2018 was announced that three scientists won the physics prize for their pioneering inventions in the field of laser technology. Among them, Professor Arthur Ashkin shared half of the prize for the invention of optical tweezers; Professor Gérard Mourou and Associate Professor Donna Strickland shared the other half for the co-invention of Chirped Pulse Amplification(CPA). As a major technological innovation to break through the bottleneck of high-intensity laser development, CPA technology since its invention has become the core technology for laser physics research, especially for ultra-fast laser research. In this article, we review the background, principle, configuration of CPA technology and applications.
