摘要：
A gyro includes a laser device for generating a first and second laser beams to be propagated circuitally in opposition directions. An electric signal is taken out from the laser device. A third laser beam having an oscillation frequency different from that of the first laser beam is led to enter the laser device so as to be propagated circuitally in the same direction as the first laser beam.
