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.

Abstract

The peculiarities have been studied of the stimulated emission of a sheetlike electron bunch of finite length and transverse size passing through an undulator field. A two-dimensional model, based on a nonstationary parabolic equation, has been formulated and includes the effects of slippage and optical guiding as well as transverse electromagnetic energy diffraction and dissipation. It is shown that the emission from the electron bunch is composed of short coherent pulses (superradiation pulses) which are diffracted after escaping from the channel formed by the electron bunch.
