Paper Abstract

Using cavity ring down spectroscopy, we recorded high resolution spectra of water overtones in the visible region. While the system is simple, experimental results have shown that the detection sensitivity is better than 2 X 10-8 cm-1. We have also studied the effects of cavity mirror reflectivity and cavity length on the detection sensitivity. The observed spectrum agrees well with the standard reference spectrum. Thus, this highly sensitive, quantitative, and widely applicable absorption spectroscopy technique proves to be capable of water vapor measurement, especially in Chemical Oxygen Iodine Laser.
