ABSTRACT:
A gas laser tube apparatus for producing a high-current glow, arc or spark which generates initiatory electrons and charged particles for establishing excitation of gas molecules in a separate region of the tube. Separate regions of ionization and excitation are established so that uniformity of excitation, optimization of the ratio of electric field intensity to electron density (E/N) and uniform intensity of excitation can be obtained in a high pressure gas laser system independent of ionization or initiation of discharge which also may need to be optimized. The separate fields are achieved by proper configuring of the electrodes with appropriate voltages applied thereto.
