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

Summary form only given. Microchip lasers represent highly efficient sources of laser radiation and are easily mass produced at low cost. However, it is difficult to operate them on a single frequency at output powers greater than about 150 mW. Hence, laser geometries that maintain the simplicity exhibited by microchip lasers yet which can be operated on a single frequency at higher output powers are of great interest. In the paper we demonstrate the potential of a birefringent filter, consisting of a Brewster plate and a birefringent crystal, as a frequency selective element in a micro-laser which has additionally, a birefringent gain crystal. Single frequency output powers greater than 760 mW have been obtained at 1064 nm for 2 W of diode laser pump power
