Evidence for Self-Focusing or Filamentation from X-Ray, 3/2 Omega o, and 2 Omega o Emission.

Abstract

With long pulse, moderate intensity Nd-laser irradiation of flat targets, time-integrated images of emission reveal filaments along the laser axis. Combined with fine-scale structure found in time-integrated images of x-ray emission, these filaments suggest self-focusing of hot spots in the incident beam.
