PULSE-PERIODIC TE-LASER Russian patent published in 2011 - IPC H01S3/977 H01S3/38 

FIELD: electricity.

SUBSTANCE: laser includes gas-filled chamber with the main discharge electrodes installed in it, charging circuit and discharging circuit. Charging circuit includes pulse voltage source and peaking capacitors. Discharging circuit includes peaking capacitors and the main discharge electrodes, at least one corona pre-ioniser in the form of dielectric tube with inner and outer electrodes. Outer electrode of pre-ioniser covers part of surface of dielectric tube and is connected to the main discharge electrode. At that, outer electrode of corona pre-ioniser is current lead of charging circuit.

EFFECT: improving efficiency of pre-ionisation and stability of operation.
