Abstract

We investigate our recently demonstrated remote air laser by studying the directional backwards and forward emission at 845nm while monitoring the atomic oxygen excitation using a microwave scattering technique. We study the high gain achieved by focusing an UV laser in air in order to produce and excite the oxygen atoms responsible for the stimulated emission, which is strongly dependent on the optical parameters of the pump. The standoff air laser can be used as a remote detector for molecular and atomic species which affect the optical propagation of the pump laser either directly or via optical stimulation.
