摘要:
A gyro apparatus has a ring laser in which laser beams of different oscillation frequencies coexist and propagate in mutually opposite circulation directions in an optical resonator, a power source of driving for the ring laser, a device for measuring a difference between the oscillation frequencies of the laser beams, and a device for controlling the power source of driving according to the frequency difference.
