Abstract
Embodiments of the invention include a system for sensing homonuclear diatomic molecules, such as, for example, nitrogen. Other embodiments include a method for sensing homonuclear diatomic molecules. The system may include a light source, a hollow-core wave-guiding device that exhibits a low attenuation at predetermined operating optical frequencies and is in optical communication with the light source, a gas introduction system for introducing a gaseous medium between the light source and the hollow-core wave-guiding device, and a detector in optical communication with the hollow-core wave-guiding device.
