ABSTRACT:
A gas laser construction includes a second anode in the vicinity of the cathode, so that current can be directed through the second anode when the laser is at low current levels, thereby assuring an adequate supply of electrons around the cathode to avoid flicker in the laser output. Current flow can be controlled between the main anode at the anode end and this second anode, so that the second anode is used only when and to the extent needed. In this way, the power output of the gas laser is more dependably controlled by controlling the current level, even at low current levels, without output flicker which would ordinarily occur.
