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

Raman backscattering (RBS) in plasma is an attractive source of intense, ultrashort laser pulses, which has the potential asa basic for a new generation of laser amplifiers.(1) Taking advantage of plasma, which can withstand extremely high power densities and can offer high efficiencies over short distances, Raman amplification in plasma could lead to significant reductions in both size and cost of high power laser systems. Chirped laser pulse amplification through RBS could be an effective way to transfer energy from a long pump pulse to a resonant counter propagating short probe pulse. The probe pulse is spectrally broadened in a controlled manner through self-phase modulation. Mechanism of chirped pulse Raman amplification has been studied, and features of supperradiant growth associated with the nonlinear stage are observed in the linear regime. Gain measurements are briefly summarized. The experimental measurements are in qualitative agreement with simulations and theoretical predictions.
