  • Measuring device having a laser and a ring resonator
    Patent number: 5004342
    Abstract: A measuring device for angular rates making use of the Sagnac-effect comprises a ring resonator (12) and a laser (10). The ring resonator (12) forms a part of the resonator cavity of the laser (10). Thereby no precautions to achieve an optical insulation between laser and ring resonator have to be taken. A semiconductor laser serves as laser. Different embodiments of the ring resonator having mirrors, an integrated optical system and a fiber optical system are described.
