On the Question of the Existence of High-Frequency Oscillations in the Power Supply Circuits of a Copper Vapor Laser and Their Influence on the Lasing Mechanism

The statement of the problem and conclusions in the publication by N. A. Yudin, M. R. Tret’yakova, and N. N. Yudin “Influence of electrophysical processes in the discharge circuit on the energy characteristics of a copper vapor laser” (Russ. Phys. J., 55 , No. 9, 1080 − 1090 (2013)) is considered. It is shown that the main positions of the publication touching on relaxation of the populations of metastable states in the afterglow and their influence on the frequency-energy characteristics of lasers are mistaken.
