Open Access research with a European policy impact...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the European Policies Research Centre (EPRC).

EPRC is a leading institute in Europe for comparative research on public policy, with a particular focus on regional development policies. Spanning 30 European countries, EPRC research programmes have a strong emphasis on applied research and knowledge exchange, including the provision of policy advice to EU institutions and national and sub-national government authorities throughout Europe.

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.
