Laser gas replenishment system |
March 24, 1992 |
| A gas replenishment system for a gas laser utilizes a gas metering device between a gas reservoir and the gas laser tube which operates at a pressure below the gas reservoir pressure. The metering device incorporates a body of gas entrapping material. The tube pressure is detected an |

Single line laser and method |
October 2, 1990 |
| A gas laser tube assembly terminates at one end with a directly affixed selectively coated curved mirror and at the opposite end with a directly affixed selectively coated half-Littrow prism oriented such that one hundred percent (100%) purity, single line, polarized light results. |

Segmented air cooled laser tube |
May 29, 1990 |
| A plurality of thin wall ceramic-metal segments are brazed together to form a gas laser tube assembly. Within each segment there is mounted a refractory metal ferrule with a central hole. The series of holes formed in the ferrules define the discharge bore. A plurality of ferrules are |

Method for assembly of laser mirrors |
January 9, 1990 |
| A gas laser tube is fitted with internal mirrors only and no windows. The laser tube is processed by heating the tube with the ends open in a vacuum oven to drive out contaminating substances. The mirrors are installed by cold welding after the tube has been decontaminated and filled wit |

Low power argon-ion gas laser |
October 16, 1984 |
| An argon-ion laser achieves low output power by using a plasma guide and mirror configuration which restricts lasing action to a portion of the resonator cavity at relatively high conversion efficiency. |

Argon-ion gas laser cathode construction |
February 28, 1984 |
| An improved argon-ion gas laser utilizes a dispenser-type cathode and within the cathode shroud mounts a preignition electrode and a heat shield enabling the cathode to be operated efficiently and within a 900.degree.-1050.degree. C. temperature range over an extended period of time. |

Segmented ceramic bore laser |
April 12, 1983 |
| A laser tube made of electrically insulating ceramic material, e.g., BeO, is formed of dry pressed and fired segments brazed together and with a chamfer or stepped area at the end of each segment adapted to interrupt the bore so as to prevent the establishment of a continuous electricall |
