摘要

A mid-infrared frequency comb is produced via an optical parametric oscillator pumped by an amplified 100 MHz Yb:fiber mode-locked laser. We use this source to make measurements of the concentration of the atmospherically relevant species of CH4 and H2O over a bandwidth of 100 nm centered at 3.25 mu m. Multiple absorption lines for each species are detected with millisecond acquisition time using a virtual-image phased array spectrometer. The measured wavelength-dependent absorption profile is compared to and fitted by a model, yielding quantitative values of the atmospheric concentration of both CH4 and H2O in a controlled indoor environment, as well as over a 26-m open-air outdoor path .
