Abstract
Silver halide (AgCl:AgBr) fibers were used for transmitting infrared radiation from a CO2 laser to an absorption cell, and from the cell to an infrared detector. The absorption of CO2 laser lines in ammonia (NH3) gas was measured in the remote cell. Use of infrared transmitting fibers for spectroscopy in the mid and far infrared and for remote sensing of gases, was demonstrated for the first time.Keywords
