Abstract
An extraordinarily high degree of spatial coherence from a high average pow
er, tabletop 46.9 nm laser was observed in two-pinhole interference experim
ents. Refractive anti-guiding and gain guiding along a capillary discharge-
produced plasma column causes a rapid increase of the spatial coherence wit
h amplifier length. Full spatial coherence was approached with a 36 cm long
plasma of very high axial uniformity and a length to diameter ratio exceed
ing 1000:1.
