Abstract:
1. A laser comprising: a ceramic body including a first wall and a second wall opposite the first wall, a first mirror positioned at first ends of the first and second walls, a second mirror positioned at second ends of the first and second walls opposite the first ends of the first and second walls, the first and second walls and the first and second mirrors defining a slab laser cavity within the ceramic body, a first electrode positioned outside the slab laser cavity and adjacent to the first wall of the ceramic body, a first heat sink thermally coupled to the first electrode, the first heat sink being positioned adjacent the first electrode with a first electrically insulating material disposed between the first heat sink and the first electrode, a second electrode positioned outside the slab laser cavity and adjacent to the second wall of the ceramic body, a second heat sink thermally coupled to the second electrode, the second heat sink being positioned adjacent the second electrode with a second electrically insulating material disposed between the second heat sink and the second electrode, and an RF power circuit configured to excite a laser gas disposed in the slab laser cavity by applying an excitation signal to the first and second electrodes, wherein the first electrode, the first electrically insulating material, and the first heat sink function as a first capacitor of the RF power circuit and the second electrode, the second electrically insulating material, and the second heat sink function as a second capacitor of the RF power circuit.
