  • Cathode construction for long life lasers
    Patent number: 4007431
    Abstract: A laser gyro is disclosed having a long life cathode located therein. The laser gyro comprises a block having a plurality of lasing tubes bored therethrough and being angularly disposed to each other to form a closed path within the block. A plurality of mirrors are positioned at the intersection of the tubes to reflect light from one tube into the next. A pair of anodes are inserted into two of the lasing tubes. A cavity is formed within the center of the block and is connected to the triangular laser path via a conduit. The cavity contains a cathode for conducting direct current to each of the anodes. These current flows energize the lasing gas to create a pair of laser beams moving in opposite directions in the closed path. The cathode is a closed end, hollow cylinder made of aluminum having a layer of oxide formed thereon by means of anodization.
