<p>A tube for a gas slab laser includes a first electrode (203b) having a first electrode inner surface and a second electrode (203a) having a second electrode inner surface. The first electrode is separated, in a first transverse direction, from the second electrode thereby defining a gap region (207) serving as discharge region (205). The tube further includes a first and a second elongated baffle member (204a, 204b), each having a respective elongated central channel (209a, 209b) formed in an inner surface thereof. Thereby discharge free stand-off regions (209a, 209b) are formed. Thereby it may inter alia be possible to prevent stray discharge and/or peripheral laser radiation (211) from coming into contact with the inner surfaces (206a, 206b) of the baffles, prevent generation of higher order laser modes and improve beam pointing stability.</p> |
