Laser beam self-focusing in gases
Abstract
A new mechanism which may cause self-focusing of laser light in gases is proposed. We adopt the view point that self-focusing in gases may result from the higher polarizability of excited atoms, and suggest that the mechanism for atomic excitation in non-linear Raman scattering. This is a multi-photon event in which many quanta are absorbed at the laser frequency and one quanta is emitted at any frequency necessary to cause excitation.
