Abstract

Stimulated absorption of spontaneous emission of a gas-discharge plasma can cause a significant increase in the population of the emitting states, compared to their population determined by inelastic collisions and spontaneous decay from upper levels. By imposing a magnetic field, this self-saturation is reduced and its contribution to the level population can be identified. The magnetic-field-dependent changes in Doppler profiles due to radiative transitions caused by saturating spontaneous emission are analyzed in the case of absorption of a weak monochromatic wave.
