Abstract

Recently, the technique of infrared/terahertz Double Resonance Spectroscopy (DRS) was proposed for remote sensing of trace gases in atmospheric conditions. The atmospheric window of transmission is in the 9-11 µm range, which makes CO2 lasers highly suited for this application. DRS is a valuable detection method because of increased measurement specificity due to terahertz ro-vibrational signature detection. Preliminary DRS measurements utilizing a pulsed CO2 laser source with a known trace gas in a vacuum chamber are discussed. A plan is then presented for future DRS experiments at ambient pressure using ultrafast laser techniques.
