ABSTRACT:
The gas laser includes in particular a cathode (2) which is substantially cylindrical about an axis (10) parallel with the axis of the laser cavity, said cathode being provided with protrusions (11) formed by grooves in which insulated conductor wires (12) are disposed, said wires being brought to an electric potential which is positive with respect to that of the cathode, and means for rotating the cathode on its axis. Cathode rotation serves to cool the cathode during operation and can also be used to circulate the active gas. Application to welding and to machining.
