ABSTRACT:
A gas-laser arrangement in which the laser medium is optically pumped. An arc or spark discharge is formed to a helix, particularly by an axial magnetic field. The volume surrounded by the helical arc or spark discharge is optically excited, unimpeded by a physical wall, by radiation from the discharge, especially in the vacuum-uv spectral region, or by resonance lines. Due to the temperature difference between the helical discharge and the gas column along the helix axis, an inversion may be produced in the vicinity of the axis by appropriate choice of gas and the gas composition.
