Abstract

A simple heterodyne spectroscopic technique that exploits the broad wings of the emission frequency profile of diode lasers is applied to the detection of atmospheric oxygen. The technique, in which we generate a radio-frequency heterodyne signal by mixing the electric fields of a diode laser and the laser-induced macroscopic polarization of an atomic or molecular ensemble, has potential applications in a number of areas, including remote sensing and monitoring of atmospheric constituents and pollutants.
