摘要
A ring laser, especially for a ring laser type of gyro, comprising a block produced from a thermally and mechanically highly-stable ceramic glass and three corner mirrors. At least one of the mirrors can be tilted about an axis by a servo-drive and one of the mirrors is a semi-transparent separating mirror, behind which is arranged a photo-detector in the beam path of the separated beam portion of one of the rotating wave trains. The photo-detector may at least be one photo-diode which is arranged in such a way that it gives an output signal proportional to the position of the beam, as a function of which an adjustment signal is formed for the servo-drive of the tiltable mirror. Two photo-diodes can be provided alongside or on top of each other in the plane of the beam. The photo-diodes are in the form of a differential photo-diode. In order to eliminate errors, one of the corner mirrors is tiltable about an axis perpendicular to the plane of the beam path.
