摘要

凝聚态物质中的高阶谐波产生(HHG)对于材料表征、全光开关和相干光源产生等各个领域的潜在应用都非常重要。要实现这些应用,必须将 HHG 与材料的特性或动态过程联系起来。在此,我们通过在光激发三维狄拉半金属(3D-DSM)中进行带间极化工程,在 HHG 与材料的瞬态特性之间架起了一座桥梁。研究发现,3D-DSM 的电子弛豫动力学可以在几百飞秒的超快时间尺度上有效地操纵 HHG。此外,时间分辨 HHG(tr-HHG)已被证明是一种跟踪电子弛豫动力学的强大光谱方法,能够识别电子热化和电子-声子耦合过程,并定量提取电子-声子耦合强度。该演示为主动控制 HHG 和测量电子动力学提供了见解。

High-Order Harmonic Generation in Photoexcited Three-Dimensional Dirac Semimetals

High-Order Harmonic Generation in Photoexcited Three-Dimensional Dirac Semimetals

High-order harmonic generation (HHG) in condensed matter is highly important for potential applications in various fields, such as materials characterization, all-optical switches, and coherent light source generation. Linking HHG to the properties or dynamic processes of materials is essential for realizing these applications. Here, a bridge has been built between HHG and the transient properties of materials through the engineering of interband polarization in a photoexcited three-dimensional Dirac semimetal (3D-DSM). It has been found that HHG can be efficiently manipulated by the electronic relaxation dynamics of 3D-DSM on an ultrafast time scale of several hundred femtoseconds. Furthermore, time-resolved HHG (tr-HHG) has been demonstrated to be a powerful spectroscopy method for tracking electron relaxation dynamics, enabling the identification of electron thermalization and electron–phonon coupling processes and the quantitative extraction of electron–phonon coupling strength. This demonstration provides insights into the active control of HHG and measurements of the electron dynamics.

期刊介绍: The Journal of Physical Chemistry (JPC) Letters is devoted to reporting new and original experimental and theoretical basic research of interest to physical chemists, biophysical chemists, chemical physicists, physicists, material scientists, and engineers. An important criterion for acceptance is that the paper reports a significant scientific advance and/or physical insight such that rapid publication is essential. Two issues of JPC Letters are published each month.
