International ClassH01S 003/08AbstractDisclosed is a mirror mounting device and method for beam path alignment of an optical cavity for a ring laser gyroscope. The ring laser gyroscope is of the type that includes a block having an optical cavity that defines a closed loop optical path. A light source directs a light beam into the path. The block includes mounting surfaces for mirrors that reflect the light beam at the optical path corners. The mirror mounting device is associated with one of the block mounting surfaces and acts to orient a concave reflective surface of one of the mirrors such that the light beam is aligned within the closed loop optical path and is at its maximum intensity irrespective of the position of the concave reflective surface of the mirror relative to its mounting surface.Other References
