In this paper, the propagation of a high intensity laser pulse in a curved plasma channel is studied. The matching conditions, which are different from straight plasma channels, are examined. The analysis includes a study of centroid and spot size oscillations, relativistic self-focusing, and the effect of wakefields on the propagation of the laser pulse. The possible application of curved plasma channels in laser wakefield acceleration is discussed. (C) 2007 American Institute of Physics.
