Phys. Rev. E 68, 026501 (2003) [4 pages]Relativistic channeling by intense laser pulse in overdense plasmasReceived 10 January 2003; revised 6 May 2003; published 29 August 2003 Channeling in overdense plasma by relativistic laser pulse is investigated. The critical laser power needed to maintain a plasma channel as well as the mode profiles of the electromagnetic fields in the channel cross section are obtained analytically. A scaling law showing that the critical power is proportional to the square of the background plasma density is found. © 2003 The American Physical Society URL:
