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

What is believed to be the first microchip-format vertical external-cavity surface-emitting laser (VECSEL) operating at 1.3 μm is reported. Fundamental-mode continuous-wave output powers >120 mW were achieved from a cavity volume ∼0.001 mm3 using a diode-pumped GaInNAs VECSEL structure capillary-bonded to a dielectric-mirror-coated single-crystal diamond heatspreader.
