Abstract
A sensor of rotational velocity on the basis of a ring laser having an external radiation path including one corner mirror of the active resonance space which is transparent to the radiation of the active resonance space and at least two corner mirrors in the external radiation path between which there is arranged a magnetically excited body consisting of a material with a magnetooptical effect to act as a bias element for the production of a phase shift. The corner mirror of the active resonance space which leads to the external radiation path has a transparency of at maximum 5% and the magnetically excited body consists of a material which can be magnetized to saturation. The body is, preferably, a Faraday cell which is constructed from a ferromagnetic compound, in particular a garnet compound.
