OPTICAL RESONATOR Russian patent published in 2012 - IPC G02F1/01 H01S3/08 G02B5/00 

FIELD: physics.

SUBSTANCE: optical resonator has a transparent flat plate bounded by total internal reflection surfaces, an optical element for inputting collimated radiation into the resonator and outputting radiation, as well as fastening elements. The number of total internal reflection surfaces is increased to 3, 4, 5 and 6, wherein said surfaces are side faces of a plate, which can be flat or arched cylindrical or spherical, while their axes of symmetry are uniformly distributed in one plane and cross at one point. The optical element for inputting and outputting radiation lies on one of these faces.

EFFECT: high Q-factor.
