FARADAY ISOLATOR WITH CRYSTAL MAGNETO-OPTICAL ROTATOR FOR LASERS Russian patent published in 2024 - IPC G02F1/09 

FIELD: laser equipment.

SUBSTANCE: invention relates to laser engineering and can be used to ensure reliable and safe operation of various laser systems, especially based on laser diodes. Essence of the invention consists in the fact that in a Faraday isolator with a crystalline magneto-optical rotator for lasers, comprising housing 1, are arranged in series on an optical axis O-O1: input polariser 11, crystalline magneto-optical rotator 13 installed in the magnetic system, and output polarizer-analyser 15, magnetic system is made of main magnet 5, input adjusting magnet 6 and output adjusting magnet 4, installed with possibility of changing distance d along optical axis O-O1 between input adjusting magnet 6 and main magnet 5 and between output adjusting magnet 4 and main magnet 5 by turning output adjusting sleeve 3 and input adjusting sleeve 7, wherein the device includes internal bushing 17, having the possibility of being rotated about the optical axis O-O1 to set the angle α between polarizing planes of input polarizer 11 and output polarizer-analyser 15.

EFFECT: simplified manufacture of the insulator and possibility of controlling the magnetic field.
