论文摘要
基于chi脉 - 脉冲波形的电磁双梳系统用于同时获得时间放大的快速传递信号和正常的光谱线形状，并从背面变换到时域。通过两个自由运行激光的差异频率混合，进行多螺旋的THZ波产生和检测。该方法用于在10 cm-1至20 cm-1（300 GHz至600 GHz）区域中获得甲酸的Thz光谱。该方法广泛适用于其他光谱区域，用于研究分子系统的瞬时动力学和光谱。
An electro-optic dual comb system based on chirped-pulse waveforms is used to simultaneously acquire temporally magnified rapid passage signals and normal spectral line shapes from the back-transformation to the time domain. Multi-heterodyne THz wave generation and detection is performed with the difference frequency mixing of two free-running lasers. The method is used to obtain THz spectra of formic acid in the 10 cm-1 to 20 cm-1 (300 GHz to 600 GHz) region over a range of pressures. The method is widely applicable across other spectral regions for investigations of the transient dynamics and spectroscopy of molecular systems.
