摘要

双梳光谱仪在光谱覆盖、分辨率和中心波长上具有灵活性，所有影响灵敏度的因素都得到了优化，可以同时从4470 nm的光谱中确定大气中CO2和N2O的浓度水平。

A Mid-Infrared Dual-Comb Spectrometer for High Sensitivity Multi-Component Trace Gas Detection

A dual-comb spectrometer with flexibility in spectral coverage, resolution and central wavelength where all affect sensitivity is optimized to simultaneously determine atmospheric concentration levels of CO2 and N2O from spectra taken at 4470 nm.
