Open Access research with a real impact on health...

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 Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

Abstract

Spin-polarized lasers offer new encouraging possibilities for future devices. We compare time-resolved luminescence measurements with theoretical models for spin dynamics in spin-polarized lasers and demonstrate ultrafast polarization switching during one short single-mode laser pulse.
