Abstract

Gas laser comprising a flat electric energizing line consisting of an insulating layer inserted between two metallic layers brought to different potentials, one of whose edges is cut out in the shape of a parabola, one slot being provided in one of the layers, an active gaseous medium flowing in the slot, a circuit for setting up a substantially punctiform discharge between the metallic layers at the level of the focus of the parabolas. The electric line is arranged on a massive plate comprising on the one hand a cut provided in its lower face substantially opposite the slot and communicating with the latter and on the other hand two grooves provided on its upper face each having fitted in it a flexible seal and arranged opposite the walls of the slot.
