METHOD OF PULSE OSCILLATION OF EMISSION OF SLOT-TYPE GAS LASER AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2011 - IPC H01S3/104 

FIELD: electricity.

SUBSTANCE: emission from slot-type discharge gap of laser is directed to one of resonator mirrors through additional passive optic forwarding section. At that, pulse generation of emission is performed by periodic interlocking of resonator emission amplification in this passive section. Device for implementation of the above method includes tight chamber filled with active gaseous medium and having an emission outlet opening and optic resonator with output mirror. Two opposite lying extended metal electrodes connected to HF generator and forming a slot-type discharge gap are installed in the chamber. Optic resonator is equipped with external passive section - optic retranslator with possibility of retranslation of distribution of intensity and phase of light beam in plane of edges of electrodes on plane of output resonator mirror installed outside the chamber, and with emission modulator installed on passive section.

EFFECT: providing the possibility of modulated change of losses in resonator of slot-type laser.
