Abstract
A gas laser has a coolable inner electrode for connection to a radio-frequency power source and a coolable outer electrode that is coaxial with and radially spaced from the inner electrode with an excitation space containing the gas to be excited in the radial space between the inner and outer electrodes. With a view to improving a laser of this type in such a way that excitation at higher power with retention of homogeneous discharge is possible, that gas decomposition is slower, and that any desired liquid coolant can be used regardless of the electrical conditions, the excitation space is radially bounded by two, tubular dielectric bodies which are coaxial with and radially spaced from each other.
