Paper Abstract

Cavity ring-down is investigated as a technique to increase the sensitivity of optical fiber gas sensors. The ring-down cavity consists of an optical fiber loop containing a micro-optic cell and an erbium-doped fiber amplifier. The erbium fiber amplifier introduces gain into the cavity to increase the ring-down times and therefore the system sensitivity. This paper reports an investigation of the system sensitivity.
