Expanding plasma as active medium of pulsed gas lasers

摘要

In this paper, sealed-off laser sources based on pulsed surface discharge with expanding plasma are described. Plasma dynamics is analyzed. Data on electron number density obtained in our experiments are presented. Experimental results on laser action in plasma are discussed. Formation of inverse population as well as influence of plasma expansion on level population are considered. A construction of laser tube with pulsed surface discharge and additional illumination lamp is proposed. Data obtained with such a tube are presented.
