Research Abstract

We develop the external-cavity system at mid-infrared wavelengths as a local oscillator in a heterodyne receiver for observations of Martian atmospheric methane and related species. Tuneability over 20cm-1 was demonstrated using a Littrow-grating setup, and which allows for good coverage of molecular transitions of methane and hydrogen peroxide. We show that its spectral stability and side mode suppression are excellent for IR heterodyne measurements.
