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.

We report the CW performance of two broadly tuneable, optically pumped VECSEL gain structures operating around 850 nm and 960 nm. We have achieved 0.75W at 852 nm in diffraction limited TEM00 mode. A tuning range in excess of 30 nm has been demonstrated with the use of an intra-cavity birefiringent filter. At 960 nm we have achieved a power of 1.75 W and a tuning range in excess of 35 nm. Stabilised single frequency operation with a line width stabilised to 85 kHz r.m.s. at the 0.5 W output power level is reported.
