Abstract :
The gas glow discharge in the powerful continuous CO2 laser is a working state of instable balance. In 1970, Meerkov proposed a method stabilizing the gas discharge process of CO2 lasers by vibrational control without feedback from a microscopic angle. In this paper, the method is applied to vibrational feedback for improving the stability of CO2 laser thermodynamics systems, thereby reducing the cooling role and raising the efficiency of laser. The method is developed from a macroscopic angle
