Observation of Relativistic and Charge-Displacement Self-Channeling of Intense Subpicosecond Ultraviolet (248 nm) Radiation in Plasmas

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 10(exp 21) cm(exp -3) and a power of approx. 3 x 10(exp 11) W the results indicate a channel radius less than 1 micrometer and a peak intensity of approx. 10(exp 19) W/sq cm. Comparison of these findings with a dynamical theory yields agreement for both the longitudinal structure and the radial extent of the propagation observed.
