Ring laser gyro cathode arrangement
Patent
·
OSTI ID:5936032
This patent describes a ring laser gyro having a body with a cavity forming a closed loop path, a cathode and a pair of anodes, each of which is in communication with the cavity and means establishing a gas discharge between the cathode and each of the anodes to provide a pair of counter-rotating beams traveling through the cavity. An improved cathode arrangement is described consisting of: a metal cathode member having a lower edge; an annular groove in a surface of the gyro body, the lower edge of the cathode member being disposed within the groove; and a cover extending about the cathode member and secured to the gyro body, the cover supporting the cathode member.
