Open Access: World leading research into plasma physics...

Strathprints makes available scholarly Open Access content by researchers in the Department of Physics, including those researching plasma physics.

Plasma physics explores the '4th' state of matter known as 'plasma'. Profound new insights are being made by Strathclyde researchers in their attempts to better understand plasma, its behaviour and applications. Areas of focus include plasma wave propagation, non-linear wave interactions in the ionosphere, magnetospheric cyclotron instabilities, the parametric instabilities in plasmas, and much more.

Based on the REF 2014 GPA Scores, Times Higher Education ranked Strathclyde as number one in the UK for physics research.

Abstract

This paper presents realisation of linearly tapered capillary discharge waveguides (CDWs), manufactured using a femtosecond laser micromachining technique. Waveguiding of a low power, 50 fs duration laser pulse is demonstrated and, despite a slight mismatch of the laser focal spot size with respect to the capillary entrance size, efficient guiding of the Gaussian-shaped laser pulse is obtained. Energy transmission of 80% is obtained for optimal delay of the laser pulse arrival time with respect to the discharge current pulse.
