FIELD: optics.
SUBSTANCE: invention relates to optical engineering, namely, to Faraday isolators for non-polarized laser radiation. Faraday isolator has series-arranged on the optical axis: a polarization beam splitter, a magnetooptical element mounted in a magnetic system made using permanent magnets, a half-wave plate and a polarization beam connector. Polarization beam splitter, the magnetooptical element and the polarization beam connector are made and installed so, that two laser beams with orthogonal polarizations pass through the said magnetooptical element in parallel at a distance ensuring mutual thermal effect of the beams on each other for reduction of temperature gradient in the magnetooptical element.
EFFECT: technical result is reduction of thermo-induced impairments of high capacity radiation passed through the Faraday isolator.
