ABSTRACT:
The generator comprises an envelope and two mirrors defining a resonant cavity, in which is maintained a monolithic wave-guide with a capillary. The capillary is formed in a thinned portion of the guide. Two electrodes extend over the thinned portion of the guide. The capillary is circular in cross section, this being obtained by drilling or extrusion of a cylindrical bar made of dielectric material. The circulation of the laser gas is excellent and the laser plasma uniform. The generator has multiple applications, for example in the medical field.
