We review tri-comb spectroscopy, a novel optical approach to nonlinear spectroscopy. This optical method that we have recently developed enables the measurement of comb resolution multidimensional coherent spectra in under one second. We show the improvement in resolution and acquisition speed by applying the method to Doppler broadened rubidium vapor. We also show how this method can be used for real-time chemical sensing applications.

三梳多维相干光谱

我们回顾了三梳光谱，一种非线性光谱的新型光学方法。我们最近开发的这种光学方法能够在一秒内测量梳状分辨率多维相干光谱。我们通过将该方法应用于多普勒展宽的铷蒸气来显示分辨率和采集速度的改进。我们还展示了这种方法如何用于实时化学传感应用。
