Abstract:

Experimental studies examining a new relativistic regime of high-intensity short-pulse propagation in plasmas have been performed that present evidence for the formation of a stable mode of spatially confined channeled propagation. For an electron density of approx. 1.35 x 10exp 21 cmexp -3 and a power of approx. 3 x 10exp 11 W the results indicate a channel radius less than 1 micrometer and a peak intensity of approx. 10exp 19 Wsq cm. Comparison of these findings with a dynamical theory yields agreement for both the longitudinal structure and the radial extent of the propagation observed.
