The thesis is dedicated to the development of new atmospheric traces monitoring device based on the cavity ring-down laser spectroscopy (CRDS) method. CRDS is a 

Cavity ring-down spectroscopy (CRDS) is a powerful technique for accurate and sensitive measurements of atomic and molecular absorption spectra. As an alternative to more traditional Fourier-transform spectroscopy (FTS) measure-ments, it has many appealing attributes. These include insensitivity to external absor ption and laser intensity noise,

Cavity ring-down spectroscopy~CRDS! is a new laser absorption technique that has the potential for the quantita-tive detection of atomic and molecular species with a high sensitivity, comparable to photoacoustic spectroscopy. CRDS was first demonstrated by O'Keefe and Deacon in 1988.1 In

Distinct locking and sampling light beams are used in a cavity ring-down spectroscopy (CRDS) system to perform multiple ring-down measurements while the
