摘　　要：飞秒强激光与物质相互作用后辐射出的高次谐波,具有单光子能量高、脉冲持续时间短、时空相干性好等特性,可以作为实验室台式化超快真空紫外和软X射线波段光源,同时高次谐波也可用于产生阿秒脉冲。这些先进光源的产生,极大地丰富了人类物质科学的研究手段。结合本课题组的高次谐波研究进展,介绍了气体高次谐波和固体高次谐波的产生原理、优化及应用。High-order harmonics generated by the interaction between intense femtosecond laser and matter have the characteristics of high single photon energy,ultrashort pulse duration,and excellent spatiotemporal coherence.It can be used as the tabletop ultrafast vacuum ultraviolet laser source and soft X-ray laser source in laboratory.At the same time,high-order harmonics are used to generate attosecond pulses.The generation of these advanced laser sources has greatly enriched the research tools of material science.In this review article,we introduce the principle,optimization,and application of high-order harmonics of gases and solids.
