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

The effects of the additive gases nitrogen and hydrogen on the gain, electron density, discharge voltage and positive-ion spectra of the plasmas of room-temperature sealed-off CO-He-Xe gas laser mixtures have been examined. Hydrogen affects the electron kinetics little, but its addition is always detrimental because the vibrationally excited CO is relaxed by V-T collisions. The effect of nitrogen is more complex; there is a beneficial CO-N2 vibrational pumping channel and a detrimental effect due to increased discharge voltage and hence gas heating. It is not a necessary additive for high-power laser operation.
