Abstract
A gas detection system uses intracavity fiber laser absorption spectroscopy. The fiber laser is stabilized by a saturable absorber, and the sensitivity is enhanced by multiple circulations of amplified spontaneous emission light under threshold conditions, and multi-longitudinal mode oscillation of the laser.
