综述固体瞬态高次谐波产生在光谱学与控制方面的进展，强调其作为可编程非线性光学平台，应用于超快动力学探测与极紫外光源等。
AI 中文摘要
固体中的高次谐波产生（HHG）已成为凝聚态物质系统中电子结构和超快动力学研究的强大探针。在本章中，我们回顾了固态HHG光谱学与控制的最新进展，重点关注半导体和强关联材料。我们讨论了HHG的理论基础，并总结了从谐波发射中提取信息的实验方法。研究表明，HHG对多种微观性质敏感，包括能带结构、跃迁偶极矩、贝里相位、晶体对称性、载流子布居、退相过程和晶格动力学。这种敏感性使得能够访问飞秒和阿秒时间尺度上的电子与结构动力学，并使HHG成为一种多功能的光谱工具。同时，HHG对许多耦合的材料和激发参数的强依赖性使得发射的谐波本质上难以与单一微观量相关联。这种敏感性不仅代表了一种局限性，也提供了众多控制的途径。我们回顾了如何利用光激发、多色驱动场、波形工程以及材料性质的瞬态修饰来增强、抑制和整形谐波发射。这些进展使固态HHG不仅作为一种光谱技术，而且作为一个可编程非线性光学平台，其应用涵盖从紧凑型极紫外光源到超分辨显微镜和超快光子器件。
英文摘要
High-harmonic generation (HHG) from solids has emerged as a powerful probe of electronic structure and ultrafast dynamics in condensed matter systems. In this chapter, we review recent advances in solid-state HHG spectroscopy and control, with a focus on semiconductors and correlated materials. We discuss the theoretical foundations of HHG and summarize experimental approaches for extracting information from harmonic emission. HHG has been shown to be sensitive to a wide range of microscopic properties, including band structure, transition dipole moments, Berry phases, crystal symmetry, carrier populations, dephasing processes, and lattice dynamics. This sensitivity enables access to electronic and structural dynamics on femtosecond and attosecond timescales and has established HHG as a versatile spectroscopic tool. At the same time, the strong dependence of HHG on many coupled material and excitation parameters makes the emitted harmonics intrinsically difficult to associate with a single microscopic quantity. Rather than representing a limitation alone, this sensitivity also provides numerous pathways for control. We review how photoexcitation, multicolor driving fields, waveform engineering, and transient modification of material properties can be used to enhance, suppress, and shape harmonic emission. These developments position solid-state HHG not only as a spectroscopic technique, but also as a platform for programmable nonlinear optics with applications ranging from compact extreme-ultraviolet sources to super-resolution microscopy and ultrafast photonic devices.
