摘要： A method and apparatus for generating a gas laser. Gas is caused to circulate in a closed cycle and circulates transversely through a resonant zone positioned on the laser axis. Gas flows through the resonant zone at subsonic speed and under simultaneous electric excitation. Magnetic pole pieces are arranged adjacent the resonant zone for controlling and stabilizing the discharge path of the laser. In the apparatus aspects of the invention an evacuated flow tunnel for closed circuit circulation of gas is provided with a resonant zone transversely across the flow path. Such zone is arranged with electric excitation means and resonator mirrors as required. Pole pieces are provided adjacent the resonant zone for guiding and stabilizing a discharge path of the laser. Blower and cooling means are also provided in the gas flow path. In a further embodiment, flow plates are aligned with the gas flow direction and placed immediately downstream from the resonant zone to assist in preventing the gas discharge of the laser path from bending out of the predetermined position.

摘要： In the disclosed gas ion laser a plurality of axially aligned electrically insulating elongated cylindrical bodies are successively disposed between a cathode housing and an anode in hermetically bonded relationship with one another and with the cathode housing and the anode to form a laser gas containing hermetic enveloping assembly. The respective cylindrical bodies define aligned discharge confining axial longitudinal bores and aligned gas return off-axis longitudinal bores isolated from the discharge confining bores except in the vicinity of the cathode housing and in the vicinity of the anode. A coolant is passed in direct contact with the outer lateral surface of the bonded cylindrical bodies in an annular coolant flow channel between the outer lateral surface of the cylindrical bodies and an annular axial magnetic field generating arrangement coaxially disposed about the cylindrical bodies. Improved gas return flow at relatively low temperature results, enabling the achievement of high efficiency, high power laser operation.

摘要： Laser amplification utilizing plasma confinement of a gas laser gain media is described. The gas laser gain media is compressed into plasma utilizing a self-reinforcing magnetic field referred to a plasma pinch (e.g., a flow stabilized z-pinch). In the pinch, the gas laser gain media is compressed to a high density, which improves the gain of the media. Coherent light is transmitted through the plasma pinch, which is amplified by the plasma pinch.

摘要： A gas laser oscillator of easy maintenance which is capable of switching a beam mode at high speed. Electric discharge sections in which gas medium is flown are formed in an optical resonating space in an electric discharge tube between a rear mirror and an output mirror. Electrodes are connected to electric discharge power sources (alternative current or direct current power sources). Coils are wound around the electric discharge tube at the respective electric discharge sections and excited by coil excitation circuits. Directions and intensities of the excitation currents from the coil excitation circuits are controlled by a controller. Regions in which the electric discharge currents flow between the electrodes in the respective electric discharge sections are varied by magnetic fields generated by the coils in accordance with the directions and intensities of the excitation currents of the coils, to thereby control the beam mode.

摘要： A high temperature laser solenoid incorporates a combination of thermally and electrically insulating components to replace and to exceed the operating limits of epoxy encapsulation which solenoid is used in cooperation with a mechanically driven cooling air flow. The solenoid construction includes a layer of high temperature resistant, electrical insulation assembled on an aluminum bobbin adapted for coil winding so as to create a solenoid. High temperature insulated magnet wire is wound into a coil on the bobbin and the coil is covered with an additional high temperature resistant, electrically insulating film layer. Wire leads are passed through notches formed through the insulation barrier and the bobbin flanges and the solenoid is covered by an intimately contacting preformed heat conductive tubular casing. Forced draft cooling is supplied to the laser assembly, and particularly to the solenoids, by a positive pressure input ventilator and a negative pressure suction fan to maintain a controlled thermal environment. The solenoid is preferably associated with a single piece laser tube for increased laser life.

摘要： A laser system having a high power output and a large volume gaseous discharge has a plurality of electrodes at each end of a channel to establish a plurality of discharges and a housing arranged to provide a continuous recirculating lasing gas flow through the channel. An ejector connected to a main circulating pump is fixed to discharge into the recirculating lasing gas flow adjacent the channel to mix lasing gas streams and cause diffusion of the gas and thereby provide a uniform plasma flow in the channel. In one embodiment, magnets are arranged to surround the channel to eliminate thermal instabilities, if they arise, and to further homogenize the lasing gas streams and insure their uniformity.

摘要： The disclosed laser anode arrangement includes a tubular anodecontaining body of ceramic material bonded to an end of an elongated cylindrical body which defines a laser gas containing discharge-confining longitudinal bore. The bore of the anodecontaining body is axially aligned with the discharge-confining bore and has a diameter greater than that of the dischargeconfining bore. An electron collecting anode surface is provided by a metal coating bonded to the inner lateral surface of the anode-containing body. The metal coating may include a base layer of a molybdenum-manganese mixture and a nickel layer bonded to the base layer. The metal coating extends around the end of the anode-containing body away from the discharge-confining body and is brazed to a metal sleeve to provide an electrically conductive path to the metal coating. A coolant such as ordinary tap water may be passed in direct contact with the outer lateral surface of the discharge-confining body and a portion of the outer lateral surface of the anode-containing body. The coolant is electrically insulated from both the metal anode coating and the electrically conductive path thereto.
