ABSTRACT:
The generator comprises an optical cavity (3, 4) resonating according to an axis (2) and two annular electrodes (5, 6) disposed along said axis, one of said electrodes (5) being provided with gas injection channels (9, 10) having injection axes (11, 12) directed toward the other electrode (6) and inclined at an angle of 45.degree. with respect to the axis (2) of the resonator, the number and the cross-section of said channels (9, 10 . . . ) being selected to enable the laser gas to be injected at supersonic speed. The operating method consists in maintaining a laser gas pressure upstream from the injection channels (9, 10) which is at least 50% greater than the downstream pressure.
