Abstract

We report two remote sensing experiments of aluminum in the winter time and trace methane in the summer time using the mobile femtosecond laser facility T&T (Terawatt & Terahertz) designed by the Defence R&D Canada-Valcartier (DRDC-Valcartier) [1]. This system is similar in many respects to Teramobile, the Franco-German laser system [2].

In the first experiment, we demonstrated the feasibility of remote filament-induced breakdown spectroscopy of aluminum targets in an open field in the winter season of Quebec-city when the outside temperature was as low as −20°C. The fluorescence signals are detected in a LIDAR configuration with aluminum target located up to 60 meters.

In the second experiment in the summer season, we remotely detected trace methane in the open field during daytime (with strong sun light) up to 20 meters.
