Compact small monolithic cemented laser gyroscope with cemented monolithic high stable and high precision laser wedge micro interferometer has described. To ensure high stability (and thus, high precision and high accuracy) against misalignment and against deformations errors, monolithic microinterferometer with wedge prism cemented with CCD and semitransparent mirror made on a long side of wedge monolithic microinterferometer prism. And for this aims monolithic wedge microinterferometer is cemented in long side (semitransparent mirror) with a ring laser with the high stability. For high stability wedge microinterferometer with ring laser is made of zero expansion material, and in the ring laser spherical mirror and a plane mirror made on different sides of a monolith zero expansion material. Laser gyroscopes are simple, low cost and easily can be manufactured in quantity.
