ABSTRACT:
A method of introducing magneto-optic bias into a ring laser permitting its se as a gyroscope. A Kerr reflective mirror is positioned in one leg of a triangle between reflectors at two vertices so that radiation from a reflector at one of the vertices is reflected at the maximum practical angle of incidence to a reflector at the adjacent vertex. By incorporating the reflective magneto-optic element at near-grazing incidence, full advantage is taken of the dependence of the magneto-optical properties upon angle of incidence.
