Target influence on TEA-CO2 laser produced plasmas in air at atmospheric pressure
Abstract
Plasma production experiments in air at atmospheric pressure, using a double discharge, Lamberton and Pearson type, TEA-CO2 laser, with xylene vapors added to the active mixture, are reported. The breakdown of air in front of an aluminum target was obtained for incident laser intensities two orders of magnitude lower than the breakdown threshold intensities in air at atmospheric pressure. The radiation driven detonation wave intensity threshold was also measured and found to be 40 MW/sq cm, in a very good agreement with values predicted by Raizer's theory.
