A ring laser gyroscope having a triangular block configuration and means to dither the block about its line of symmetry. The triangular block is configured to be symmetrical about its axis of symmetry to reduce the temperature gradient across the instrument, which effect causes output signals in the absence of an input angular rate. An optical wedge attached to the output reflector of the triangular block and an external output prism form an interferometer by means of which the sensitivity of the device is reduced and the interferometer signal made equal and opposite to that of the laser cavity.
