An experimental technique for recording the temperature dependence of linear response of symmetric two-arm DC discharges in a ring helium-neon laser on external harmonic disturbance in the temperature ange from minus 27 to 84 °С is developed. A technique was developed in which a critical temperature value was found for each current value. The condition for the development of oscillatory instability in a chain is analyzed. The necessity to take into account the effect reported in choosing conditions for maintaining a discharge in ring lasers is shown. The range of conditions corresponding to a stable symmetric two-arm DC discharges in a ring helium-neon laser is determined.
Key words: ring laser, delayed process, ionization instability, positive column, bilateral dc discharge.
