Experimental studies examining a anew relativistic regime of high-intensity short-pulse propagation in plasmas have been performed which present evidence for the formation of a stable mode of spatially confined (channeled) propagation. For an electron density of {similar to}1.35{times}10{sup 21} cm{sup {minus}3} and a power of {similar to}3{times}10{sup 11} W, the results indicate a channel radius ,1 {mu}m and a peak intensity {similar to}10{sup 19} W cm{sup 2}. Comparison of these findings with a dynamical theory yields agreement for both the longitudinal structure and the radial extent of the propagation observed.
