ABSTRACT:
A cavity length control assembly for a ring laser gyro includes a mirror support to which a piezoelectric plate is mounted. The piezoelectric plate is mounted at a center post of the mirror support with a preload tension. An outer perimeter of the piezoelectric plate is supported against the perimeter of the mirror support, thereby permitting the piezoelectric plate to exert axial force against the perimeter, without being radially restrained at the perimeter.
