Abstract
In this paper, fiber-optic cavity sensor based on cavity ringdown spectroscopy for monitoring hydrogen diffusion has been introduced. An external cavity diode laser (ECDL) has been used as tunable laser source (1520-1600 nm). The temporal evolution of the hydrogen diffusion out of the silica-based fiber cavity has been studied by measuring the ringdown times at different wavelengths every 24 h. The ringdown times are compared with a theoretical diffusion model. It has good agreement with the experimental results.
