Abstract

A Tm-Ho co-doped optical fiber laser exhibits significant fluorescence between 1.6 and 2.1 μm. Such a fiber can from the basis of a gas detection system, since many gases of interest have overtone absorption bands in this wavelength region: in particular, carbon dioxide, methane, arsine, replacement gases for refrigerants, and nitrous oxide. Using this fiber we have demonstrated a simple scheme for the detection of overtone absorption bands of carbon dioxide in the 2 μm region. The detection sensitivity for carbon dioxide with this present method is of the order of 1%.
