Thermal Self-Focusing of a Laser Beam in a Dense, Low Temperature Plasma.

Abstract

The thermal self-focusing of a Gaussian electromagnetic beam incident upon a dense, low temperature plasma is discussed. The behavior of the beam as it propagates through the plasma is analyzed. A measure of the penetration depth of the beam in an inhomogeneous plasma as a function of its power is given. (Author)
