摘　　要：超快激光在极短的时间内能够达到极高的功率,可以揭示极端的光与物质的相互作用,具有先进的材料加工能力,是产生极紫外(XUV)和高次谐波(HHG)脉冲的理想驱动源,在医疗诊断方面也具有广阔的应用前景。钛宝石(Ti:Sa)激光器自诞生以来,一直是超快激光研究的主流方向,其脉冲宽度很容易达到小于50 fs,但平均功率一直限制在数瓦水平,这限制其在更广泛领域中的应用,掺镱(Yb)晶体激光器的后压缩技术提供了一种获得高平均功率和高峰值功率飞秒脉冲的新方案。随着多通腔(multi-pass cell,MPC)非线性脉冲压缩技术的提出,采用掺镱晶体激光器和MPC非线性脉冲压缩技术相结合产生高功率超短脉冲的方案逐渐得到发展并获得了不错的结果,使实现平均功率超过数千瓦、单脉冲能量达到焦耳量级、脉冲宽度短至几十飞秒的超短超强脉冲成为可能。在文章中,主要介绍了MPC的基本原理,回顾MPC非线性脉冲压缩技术的最新研究进展,并指出该技术的未来发展方向以及前沿应用。Ultrafast laser can achieve extremely high power in an extremely short time,revealing the extreme interactions between light and matter.They possess advanced material processing capabilities and are ideal driving sources for generating extreme ultraviolet(XUV)and high-order harmonic(HHG)pulses,with broad application prospects in medical diagnostics.Since its inception,the titanium sapphire(Ti:Sa)laser has been a mainstream direction in ultrafast laser research,with pulse widths easily reaching below 50 fs.However,the average power has been limited to a few watts,which restricts its application in broader fields.The post-compression technology,with the introduction of multi-pass cell(MPC)nonlinear pulse compression technology,the combination of ytterbium-doped crystal lasers and MPC nonlinear pulse compression technology,has gradually developed into a promising solution for generating high-power ultrashort pulses.This has yielded impressive results,making it possible to achieve average powers exceeding several kilowatts and single pulse energies.The basic principles of MPC are mainly introduced,the latest research progress in MPC nonlinear pulse compression technology is reviewed,and the future development directions and cutting-edge applications of this technology are pointed out.
