研究目的
Understanding the microscopic mechanism of solid-state harmonics and its applications in probing electronic structure, ultrafast dynamics, and developing novel light sources.
研究成果
Solid-state HHG has emerged as a promising field for attosecond science and compact short-wavelength light sources. The review highlights the progress in understanding the mechanisms, the potential for probing electronic structures, and the future prospects including the use of engineered materials and high-repetition-rate lasers for applications in ultrafast spectroscopy and imaging.
研究不足
The paper discusses the challenges in understanding the exact mechanisms of solid-state HHG, including the roles of electron correlations and propagation effects. It also mentions the limitations in extending the high-energy cutoff due to material damage thresholds and self-absorption of XUV photons.
