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

Active control of key laser output beam parameters, such as optical power and transverse intensity profile, of a continuous-wave (CW) Nd:YAG laser is reported. This was achieved by accurately controlling the surface profile of an intracavity MEMS micromirror through active control of its substrate temperature. An output power variation (>20%) and a significant modification of the transverse mode profile could be observed for a temperature variation of 35 °C.
