METHOD FOR INCREASING RELIABILITY OF DISCHARGE IGNITION IN RING GAS LASER WITH TWO GAS-DISCHARGE GAPS Russian patent published in 2024 - IPC G01C19/64 H01S3/83 

FIELD: laser equipment.

SUBSTANCE: ring gas lasers. A method for igniting a discharge in a ring gas laser with two gas-discharge gaps, a common cathode and separate anodes, and an ignition electrode in each gas-discharge gap includes applying a pulsed positive discharge ignition voltage to the ignition electrodes, establishing a positive voltage at the anodes and a negative voltage at the cathode to maintain a constant discharge current. Before simultaneous ignition of the discharge in both gas-discharge gaps, the discharge in each gas-discharge gap is alternately ignited and extinguished by applying a positive pulse voltage to each of the ignition electrodes separately and then removing the negative cathode voltage.

EFFECT: increasing the reliability of discharge ignition in a ring gas laser with two gas-discharge gaps and eliminating the possibility of a discharge occurring in the bypass channel of the ring gas laser.
