Fast-flow axial high-power CO2 laser

摘要

The invention relates to a fast-flow axial high-power CO2 laser having at least one discharge tube (11) through which laser gas flows and to which in each case one cathode (27) and anode are allocated, which are connected to a high-voltage source. Preferably in the case of high-power lasers, in order to stabilise the laser power and in order to avoid inhomogeneities occurring at the cathode (27), the cathode (27) is constructed as a hollow cathode.
