Proposed in the present work is a method for laser radiation guiding in a density channel formed in plasma by a relativistic electron beam. The conditions and parameters of the relativistic beam ensuring the guiding by means of the proposed method have been examined.8 pages, no figures; submitted to Phys.Rev.LettPlasma PhysicsOpticstext
