摘要

一种新型的2.6 ~ 10 μm波长可调的亚70 fs脉冲激光源与中红外外差检测相结合，为宽带二维傅里叶变换红外光谱测年提供了一个通用的激光平台。中红外激光输出可作为短脉冲驱动器和宽带探针，用于时间分辨研究超快分子相干性、种群动力学和大量复杂分子系统中的多模态能量转移。

Broadband two-dimensional spectrochronography with ultrashort pulses in the mid-infrared

A novel, 2.6-to-10-μm wavelength-tunable laser source of sub-70-fs pulses is combined with mid-IR heterodyne detection to provide a versatile laser platform for broadband two-dimensional Fourier-transform infrared spectrochronography. The mid-infrared laser output serves as both a short-pulse driver and a broadband probe for time-resolved studies of ultrafast molecular coherence, population dynamics, and multimodal energy transfer in a vast class of complex molecular systems.
