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 ∼1.35×1021 cm-3 and a power of ∼3×1011 W, the results indicate a channel radius ,1 μm and a peak intensity ∼1019 W cm2. Comparison of these findings with a dynamical theory yields agreement for both the longitudinal structure and the radial extent of the propagation observed.
