Intense laser self-focusing in plasmas
Abstract
Strong evidence is reported for the self-focusing and filamentation of intense laser beams in coronal plasmas obtained from second harmonic emissions from 1.06 micron laser-plasma interactions. The experiments utilized one-dimensional spatially resolved second harmonic spectra and two-dimensional spatially resolved second harmonic images. The effect of target atomic number, target shape, and prepulse-induced precursor plasma corona on the self-focusing and filamentation processes was also investigated.
