Abstract

There was developed a three-electrode discharge CO₂- laser of atmospheric pressure. The discharge in the gaps was ignited sequentially in time at the application of high- voltage pulse to the middle control electrode. A storage capacitor of the main discharge is connected directly to the other two electrodes. The system and the operation method allow to form the discharge with the input energy up to 250 J/I-atom with 11,5% laser efficiency. The voltage on the main laser electrodes before the discharge ignition was in the range of 0.6...0.9 of the static breakdown voltage for the laser medium. The energy for the discharge formation was only 1...3% of the stored pump energy. Such system and the operation method can reduce by tens of times the load on the switches in the CO₂-laser.
