ABSTRACT:
A new concept of gyroscope utilizing self-modulation is introduced in a frame of a solid state ring type laser. The inventive solid state ring laser system includes a base, a laser pumping source, an active medium, a focussing unit, a detector, a magnet and a cover, wherein the magnet having an appropriate magnetic field strength to distinguish the direction of rotation and to increase the sensitivity. In the inventive gyroscope, a direct sensing of rotation is made by measuring the self-modulation frequency without complex signal processing by using a frequency counter.
