Absorption at Optical Wavelengths in a Plasma Aerosol.

Abstract

The absorption of radiation at optical wavelengths (3 cm to 0.3 micrometers)in a plasma aerosol is examined. In particular, the mean free path is plotted as a function of wavelength for temperatures appropriate to laser-induced gas breakdown. Various formulae, one assumption used in their derivations, and their regions of validity are discussed. Keywords: Atmospheric absorption; Laser radiation; Air breakdown; Plasma containment; Laser induced plasma; Absorption coefficients.
