Abstract

A mid-infrared (Mid-IR) spectroscopy system based on optical frequency comb technology is being developed. Using nonlinear optical interactions, the light source in the system generates a tunable optical frequency comb in the Mid-IR wavelength range (λ = 2.5 – 10 μm). The characteristics of this light source (highly coherent, accurately defined frequencies) render the system ideal for use in many applications such as trace gas detections with a long absorption length and high resolution spectroscopy for identification of unknown molecules.
