摘要
2018年度诺贝尔物理学奖的一半授予了法国科学家莫罗(G.Mourou)和加拿大科学家斯特里克兰(D.strickland),以表彰他们对超短超强激光领域的奠基性贡献。他们发明的啁啾脉冲放大(CPA)方法解决了飞秒激光放大的问题,使得超快走向超强,诞生了超短超强激光新技术,也改变了人类的生活。文章将从新的视角解读飞秒激光放大的CPA方法,分析该领域的研究现状,讨论其未来创新发展趋势,深度思考如何拓展超短超强激光的能力边界。
In 2018, half of the Nobel Prize in Physics was awarded to Gérard Mourou and Donna Strickland for their groundbreaking technology involving intense ultrafast lasers. The chirped pulse amplification(CPA) scheme they invented has enabled ultrafast femtosecond lasers to reach ultrahigh peak-powers, which has not only given birth to new technology but also benefited mankind. This paper will interpret the CPA scheme from a fresh perspective, and review the current status as well as the future development of ultrafast intense lasers. We will analyze in depth how to pioneer and push the field of CPA to even further frontiers.
