Abstract:
1. A tube for a slab laser comprising: a first electrode comprising a first electrode inner surface; a second electrode comprising a second electrode inner surface, wherein the first electrode is separated, in a first transverse direction, from the second electrode thereby defining a gap region having a gap thickness between the first electrode inner surface and the second electrode inner surface; a first and a second elongated baffle member, each comprising a respective elongated central channel formed in an inner surface thereof; wherein the first and second elongated baffle members are disposed in the gap region along a first and a second longitudinal edge portion, respectively, of the first and the second electrode, respectively; and wherein the first and second elongated baffle members are disposed with their inner surfaces facing the gap region such that the inner surface of the first electrode, second electrode, first baffle member, and second baffle member cooperate to surround the gap region; wherein the elongated central channels of the baffle members serve to extend the gap region in a second transverse direction by a depth of the elongated central channels thereby defining stand-off regions in the channels that extend along the length of the baffle members in the longitudinal direction; wherein inner surfaces of the baffle members cooperate to reduce acoustic oscillations of a gaseous lasing medium disposed in the gap region; and wherein the elongated central channel of each baffle member runs along the length of an inner surface of the bridge members, and wherein the inner surfaces of the elongated central channels cooperate to reduce acoustic oscillations of a gaseous lasing medium disposed in the gap region.
