Strathclyde Open Access research that creates ripples...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of research papers by University of Strathclyde researchers, including by Strathclyde physicists involved in observing gravitational waves and black hole mergers as part of the Laser Interferometer Gravitational-Wave Observatory (LIGO) - but also other internationally significant research from the Department of Physics. Discover why Strathclyde's physics research is making ripples...

Strathprints also exposes world leading research from the Faculties of Science, Engineering, Humanities & Social Sciences, and from the Strathclyde Business School.

Abstract

We present a promising approach to scaling the power of modelocked lasers by operating them quasi-cw. This could match the pulse repetition rate requirements of many applications. Active stabilisation is then deployed to minimise the time taken to reach a steady cw state. An intracavity acousto-optic Q-switch was used to modulate the laser loss in response to laser spiking.
