  • Ionic conduction barrier for ring laser gyroscope bodies
    Patent number: 5432604
    Abstract: A ring laser gyroscope has an electrically insulating barrier ring placed between the grounded metal mounting device and the frame, which is formed of a lithium aluminosilicate material that contains mobile ions. The barrier ring prevents migration of the ions from the frame material to the mirrors that are used to direct the counterpropagating waves around the closed path in the ring laser gyroscope.
