ABSTRACT:
In the disclosed laser gyrometer, the three resonant optical cavities of the block are connected to a cathode chamber by means of the three cathode capillary tubes and to a balancing chamber by means of three balancing capillary tubes. The axis of the cathode is identified with the axis of actuation. The block is actuated by means of an actuating ring in thermal contact with the cathode so as to provide for dissipation of the heat generated at the cathode. The invention makes it possible to solve the problems relating to wobble (or lack of dynamic balance) as well as thermal gradients.
