Abstract

We demonstrate a fiber laser system for the detection of the greenhouse gas, nitrous oxide (N2O), at sub-ppmv concentration levels. The fiber laser is stabilized by a saturable absorber. The sensitivity is enhanced by multiple circulations of amplified spontaneous emission light under threshold conditions, and multi-longitudinal mode oscillation of the laser. An intra-cavity Herriott cell of an effective path length of 30 m was used to detect the P (12) rotational line of N2O at ∼1522.20 nm.
