Claim 0:
1. An apparatus for guiding charged particles, comprising a substrate having a surface;
a layer on the surface;
an inhomogeneous channel formed by two mutually opposite delimiting structures on a side of the layer that is opposite the substrate;
a radiation device which is designed to generate at least one pulsed laser beam and inject the at least one pulsed laser beam into the channel from a side that is opposite the layer, wherein the layer, for the at least one laser beam, is optically thin and the surface is partially reflective, such that the surface brings about an at least partial reflection of the at least one laser beam for guiding the charged particles, wherein the delimiting structures have a high optical density in comparison with the layer,
and wherein the delimiting structures are designed to guide the particles by means of the at least one laser beam in the channel and thereby alternatingly focus them along the channel and in at least one direction perpendicular to the channel.
