对角切片四波混频：相干展宽机制的自然分离
Diagonal Slice Four-Wave Mixing: Natural Separation of Coherent Broadening Mechanisms
摘要：
我们提出了一种超快相干光谱数据采集方案，该方案对多维相干光谱中使用的时域切片进行采样，以实现比全光谱更快的数据收集。我们推导出解析表达式的共振线型使用这种技术，完全分离均匀和不均匀的扩大贡献到单独的投影线型任意不均匀的扩大。这些线形表达式也适用于从全多维光谱中获取的切片，并允许直接测量那些光谱中以及我们自己的光谱中的线形参数。
英文摘要：
We present an ultrafast coherent spectroscopy data acquisition scheme that samples slices of the time domain used in multidimensional coherent spectroscopy to achieve faster data collection than full spectra. We derive analytical expressions for resonance lineshapes using this technique that completely separate homogeneous and inhomogeneous broadening contributions into separate projected lineshapes for arbitrary inhomogeneous broadening. These lineshape expressions are also valid for slices taken from full multidimensional spectra and allow direct measurement of the parameters contributing to the lineshapes in those spectra as well as our own.
