ABSTRACT:
A gas discharge tube for a gas laser includes a discharge chamber having a first end and a second end. A cathode is mounted near the first end in a cathode region of the discharge chamber and an anode is mounted near the second end. An electromagnet induces an axial magnetic field within the discharge region, and a pole piece is mounted on the end of the electromagnet adjacent the cathode region. By using a pole piece for attenuating the axial magnetic field in the cathode region, a significant reduction in 60-60 Hz modulation of the light beam is realized, as well as a reduction of sputtering in the throat region of the discharge tube, additionally, the cathode placement relative to the throat region may be optimized leading to an increase in plasma tube efficiency. In addition, a second pole piece is mounted on the end of the electromagnetic coil, adjacent the anode region, for attenuating the axial magnetic field inside the anode region after the discharge reaches the anode.
