Open Access research that is helping to improve educational outcomes for children

Strathprints makes available scholarly Open Access content by researchers in the School of Education, including those researching educational and social practices in curricular subjects. Research in this area seeks to understand the complex influences that increase curricula capacity and engagement by studying how curriculum practices relate to cultural, intellectual and social practices in and out of schools and nurseries.

Research at the School of Education also spans a number of other areas, including inclusive pedagogy, philosophy of education, health and wellbeing within health-related aspects of education (e.g. physical education and sport pedagogy, autism and technology, counselling education, and pedagogies for mental and emotional health), languages education, and other areas.

Abstract

Presented is the power-scaling characteristics of microchip vertical external-cavity surface-emitting lasers which include grating apertures for mode selection. Multi-Watt multi-lateral-mode emission at a wavelength of 1060 nm is obtained with sub-linear increase in maximum output power with aperture-size. It is also shown that the polarisation is only set by the grating lines for high-order modes which interact sufficiently with the grating.
