Title: CAVITY RINGDOWN SPECTROSCOPY: A LOOK INSIDE THE CAVITY

Abstract: The technique of Cavity Ringdown Laser Absorption Spectroscopy (CRLAS) has experienced rapid growth in recent years, both in terms of users as well as the range of applications. The technique offers exceptional versitility in use, resulting from the simplicity of execution. In this talk I will review the early development of the technique, providing a connection between where it came from and where it might go in the future. Present applications ranging from the ultra violet to the mid-infrared will be discussed, with emphasis on the developments in the infrared region. The difficulties and advantages of working in the infrared will be discussed. Limitations caused by the lack of easily tuned pulsed light sources, background absorptions, and by mirror reflectivities, will be considered. Finally, recent speculation on the role that frequency interference plays in the ringdown process will be discussed. This will include a discussion of the limitations imposed by coherent interference as well as how other non-linear interactions could potentially improved performance in some applications.
