ABSTRACT:
An improved laser gain tube for use in a differential laser gyro is disclosed. The gain tube comprises a housing having a cathode located therein with a pair of chambers located within the cathode, a pair of discharge tubes extending from anode regions on each side of the cathode into each of the chambers and means for providing an electrical discharge within the chambers. An aperture positioned between the chambers is adapted to provide optical communication therebetween while maintaining electrical isolation of an electrical discharge in each chamber. The chamber walls are adapted for maintaining the discharge with a current density below the threshold for cathode sputtering.
