    摘要： A folded slab waveguide laser having a hybrid waveguide-unstable resonator cavity. Multiple slab waveguides of thickness 't' supporting vertical waveguide modes are physically arranged above one another in a stack and optically arranged in series through one or more cavity folding assemblies 20a with curved mirrors 22a, 22b. A gain medium such as a gas is arranged in each slab. Each cavity folding assembly 20a is designed to redirect the radiation beam emitted from one slab waveguide 10a, 10b into the next 10b, 10a and also at the same time to provide a focus for the radiation beam so that a selected vertical waveguide mode (or modes) is (or are) coupled efficiently into the next slab.

    摘要： A radio-frequency, RF, slab laser 10 in which the electrodes form an integral part of the vacuum enclosure. First and second electrodes 12, 14 have respective internal surfaces 22, 24 and external surfaces 23, 25. The internal surfaces 22, 24 lie in the vacuum enclosure and form a gap to support a plasma discharge 18. The vacuum enclosure is constructed by a first part, integral with the first electrode 12, and a second part, integral with the second electrode 14, so that the electrode external surfaces 23, 25 lie outside the vacuum enclosure. An RF source 50 can thus supply an RF drive current to the external surface 23 of the first electrode 12 obviating the need for a vacuum feedthrough and also allowing inductors to be fixed on the outside the vacuum enclosure where they can be removed and replaced to achieve impedance matching without disturbing the cavity components.

    摘要： A radio frequency, RF, slab laser comprising a live electrode (102) and a ground electrode (108) whose inwardly facing surfaces face each other to form a gap for forming a plasma discharge when the live electrode is supplied with a suitable RF drive signal. The electrodes are enclosed in a vacuum space by a vacuum housing (114) with an access aperture (116). The access aperture is sealed with a vacuum flange (70) that comprises an electrically insulating connector. A plurality of hollow conductors (62) are arranged to extend through the vacuum flange into the vacuum space and connect with the live electrode. The hollow conductors connect to the live electrode to supply it with its RF drive signal and also coolant fluid which is distributed through fluid circulation channels (80a, 80b). Coolant fluid is supplied to the live electrode through certain ones of the hollow conductors and taken out by others.
