Abstract

Modal and focusing properties of the plasma based waveguide having a parabolic profile of the electron density are treated for x-ray beams with the ray-transfer and paraxial-envelope equations. Conditions on the single mode, multimode and leaky mode propagation in straight and tapered plasma channels are evaluated. The near- and far-field patterns of these modes are calculated. The main result is that the mode structure is guide length and wavelength dependent, resulting in the guide length and wavelength dependent conditions for the guiding and focusing. The modal analysis finds its application in the field of x-ray lasers, extremly high harmonic generation and x-ray beam focusing, in which it may be helpful to design guides for optimum beam propagation. Futhermore, the mode properties are extremly simple and provide an idealised model for the real plasma waveguides.
