光学多维相干光谱是研究原子、分子、半导体材料和复杂系统的结构、性质和超快动力学的有力手段。多维相干光谱的当前实现具有长的采集时间和/或有限的光谱分辨率。此外，大多数技术利用复杂的几何结构或相位循环方案来隔离非线性信号。我们展示了一种新的方法，使用频率梳进行快速，高分辨率和背景自由的半导体材料的多维相干光谱。我们的方法受到双梳光谱的启发，双梳光谱已被证明是一种多功能的工具，用于在短的采集时间内获得高分辨率的一维吸收光谱。我们使用GaAs多量子阱样品演示了该方法。
Optical multi-dimensional coherent spectroscopy is a powerful technique for studying the structure, properties and ultrafast dynamics of atoms, molecules, semiconductor materials and complex systems. Current implementations of multi-dimensional coherent spectroscopy have long acquisition times and/or limited spectral resolution. In addition, most of the techniques utilize complex geometries or phase cycling schemes to isolate non-linear signals. We demonstrate a novel approach of using frequency combs to perform rapid, high resolution and background free multi-dimensional coherent spectroscopy of semiconductor materials. Our approach is inspired by dual-comb spectroscopy, which has been proven to be a versatile tool for obtaining one dimensional absorption spectra with high resolution in a short acquisition time. We demonstrate the method using a GaAs multi-quantum well sample.
