Asymmetry of the Optical Transmission Spectra of a Pulsed Discharge With an Extended Hollow Cathode During at Resonance Interaction of Short Polychromatic Laser Pulses With Excited Neon Atoms

Abstract

The processes of resonant interaction of short pulses of polychromatic radiation of a dye laser with plasma of a nanosecond discharge in neon with an extended hollow cathode are experimentally studied. During the propagation of laser radiation inside the cathode cavity near the spectral absorption line of Ne I with a wavelength of 650.6 nm, the formation of asymmetric optical transmission spectra of the plasma of the dispersion type are detected, while during the propagation of laser radiation in the region between the electrodes, symmetric transmission spectra of the classical kind are formed.
