Abstract
PURPOSE:To give nonelectrodic nature and longer life to a gas laser tube, by mounting more than a pair of outside electrode outside a plasma fine tube and secondary electron radioactive materials inside the tube, and exciting high frequency discharges. CONSTITUTION:A pair of outside electrode 3, 3' is mounted on each outer side of a vacuum outer container 2 which acts as a plasma fine tube containing gaseous laser media 1. A high frequency current is fed to the electrode 3, 3' from a high frequency oscillator 4 to create high frequency excitation. At the time, the secondary electron radioactive materials 11, 11' are mounted inside the plasma fine tube corresponding to the electrodes 3, 3'. When discharge occurs between the electrodes 3, 3' owing to the high frequency excitations, the secondary electrons are discharged from the materials 11, 11' to make uniform the discharges in the laser tube easily and reduce the voltage decrease in the tube and lower the high frequency current to be applied to the electrode 3, 3'. With such an arrangement, because no electrode is contained within, the structure becomes simpler and no gas pressure lowering owing to absorption of gas to electrodes occurs, and longer life on the part of the tube can be realized.
