SELF-LOCKING AND OTHER MODES OF THE LASER OSCILLATIONS

In this paper experiments are presented on stability of laser generation at 632.8 nm for the He-Ne tube with high amplifying coefficient. The experiments show that without any outer stimulation full stability of laser generation is obtained when self-locking is settled. Self-locking requires some conditions to be fulfilled for the cavity mirrors, i.e., their transmittivities and positions. The latter are the main subject of the experiments presented here. The results of an experiment show that in self-locking pi pulse is generated and forms swept absorption at 632.8 nm in the He-Ne discharge.
