Tubular laser
Patent
·
OSTI ID:7276318
A gas laser, including a laser capillary tube, is described that has a laseable gas filled bore and laser and an anode carried by the laser capillary in communication with the gas filled bore, and mirror end pieces, a cathode envelope surrounding an end of the laser capillary tube and a cathode in the cathode envelope. The improvement in the laser consists of an annulus integral with the cathode envelope, the annulus having an internal diameter greater than the external diameter of the laser capillary tube so as to form a cylindrical space between the capillary tube and the annulus, and a low temperature inorganic solder glass sealant filling the cylindrical space and forming a unitary support and seal for the laser capillary tube in the cathode envelope between the ends of the laser capillary tube, whereby one of the laser mirror end pieces is contained in the cathode envelope and the other laser mirror end piece is external of the cathode envelope.
