  • Gas laser arrangement
    Patent number: 4937838
    Abstract: A gas laser arrangement includes a discharge tube between a cathode and an anode, the discharge tube including a central discharge channel and at least one gas return channel. A blocking electrode is provided at the openings of the gas return channels at least in the cathode space and possibly also in the anode space, the blocking electrode being connected to a blocking voltage to avoid misfirings of the laser through the gas return channels.
    Type: Grant

  • Magnetic field source for an ion laser
    Patent number: 4847841
    Abstract: An ion laser includes a magnetic field source to generate an axial magnetic field in one region and transverse field components outside the region, the magnetic field source being shorter than the discharge channel of the laser. Axially spaced permanent magnets in the proximity of the discharge channel are adapted to the laser structure and can include magnetic rings or ring structures. The magnets are preferrably adjacent the cathode end of the discharge channel.

  • Gas laser arrangement
    Patent number: 4841540
    Abstract: A gas laser arrangement includes a discharge tube arranged between a cathode and anode and including a central discharge channel and at least one gas return channel. An auxiliary electrode for pre-discharge is allocated to the cathode, the auxiliary electrode being connected to an operating voltage source through a resistor.
