Acceptance Angle of a Plasma Channel
Abstract
Plasma channels are useful as guiding structures for high intensity electromagnetic radiation. A finite radius plasma channel ceases to act as a guiding structure if the f-number of the focusing used to couple radiation into the channel is too small. Expressions are derived for the critical f-number needed to achieve guiding in a finite radius plasma channel. This is done using both a ray tracing analysis, and an eigenmode expansion technique.
