Experiments on Self-Focusing in Laser-Produced Plasmas

  • A. J. Alcock

Abstract

Recent investigations of laser induced gas breakdown have revealed a number of phenomena which are compatible with the occurrence of self-focusing at the time of breakdown. Some examples of the effects observed are: 90° scattering of laser light from regions having transverse dimensions as much as an order of magnitude less than the diameter of the focal volume, intense forward scattered radiation at a wavelength close to that of the laser, and plasma filaments of ∿10μ diameter which have been detected by means of high spatial resolution, sub-nanosecond, Schlieren photography and interferometry. In this talk the large amount of experimental evidence for self-focusing is reviewed and a number of possible mechanisms discussed.
