Fourier transform spectroscopy around 3 microns with a broad difference frequency comb

Optics 2015-06-15 v1 Chemical Physics

Abstract

We characterize a new mid-infrared frequency comb generator based on difference frequency generation around 3.2 microns. High power per comb mode (>10-7 W/mode) is obtained over a broad spectral span (>700 nm). The source is used for direct absorption spectroscopy with a Michelson-based Fourier transform interferometer.
