Abstract
Investigation of the Effect of Particle Contaminants on Laser- Induced Air Breakdown. Technical rept. 22 Jun 71-30 Aug 72, Feiock, Frank D. Goodwin, Lester K.

Calculations were performed using a one-dimensional, Lagrangian, hydrodynamic code developed for the study. The results of this study indicate that the interaction of a laser beam with atmospheric contaminants such as SiO2 and Al2O3 can supply a primary electron density that will lead to a significant decrease in the laser-induced breakdown threshold for air.
