DEVICE AND METHOD FOR DISPOSAL OF OPTICAL DISCHARGE OSCILLATIONS Russian patent published in 2020 - IPC H01J61/02 H01J65/04 G01J3/10 

FIELD: physics.

SUBSTANCE: invention relates to devices and a method of eliminating oscillations of optical discharge used to obtain broadband optical radiation with high spectral brightness, and is of interest for applications in microelectronics, spectroscopy, photochemistry and other fields. Device for eliminating oscillations of optical discharge consists of discharge chamber, close in shape to spherical, transparent for input laser radiation and output optical radiation, filled with gas mixture of one or more lasers located outside the discharge chamber, the radiation of which is focused near the center of the discharge chamber. Device additionally comprises sealed external reservoir, which is also connected to discharge chamber by means of tube, and internal diameter of discharge chamber is more than horizontal cross-section of front of temperature of gas heated by optical discharge at the level of its center, but less than its double section, wherein discharge chamber is made of material with high heat conductivity.

EFFECT: improved characteristics of the stabilization process, namely elimination of oscillation instability of the optical discharge and improvement of its spatial stability due to use of an external backup volume.
