TAPPED GAS LASER WITH CROSS DISCHARGE Russian patent published in 1994 - IPC

FIELD: quantum electronics. SUBSTANCE: long service life is achieved due to improvement of efficiency of regeneration of CO₂ in the whole volume of discharge channel and in surrounding. Laser has discharge channel formed by electrodes and ceramic plates. Stabilizers of gas content are made in form of hollow cylinders and mounted onto surface of electrode being external relating to discharge channel. Distance l₁ between two nearest stabilizers and distance l₂ between any stabilizer and the discharge channel is chosen from the relation l₁≅ k/p≥ l₂, where K is proportionality coefficient being equal 5·10² mm Hg x mm, p is active medium pressure, mm Hg. EFFECT: prolonged service life. 2 dwg
