Ultra stable resonant cavity for gas analysis systems
Abstract
Systems and methods for detecting trace gases utilize a resonance optical cavity and a coherent light source coupled to the cavity through a cavity coupling mirror. The cavity is constructed of a material having the same or a similar coefficient of thermal expansion as the mirror elements defining the cavity. The main (bulk) cavity material may be the same as the main (bulk) material that forms the mirror elements, or it may be different. Such resonant cavity configurations provide improved accuracy and stability as compared to existing cavity configurations based upon similar principles.
