Pr2 (2001): 123-126.http://hdl.handle.net/10217/67485An extraordinarily high degree of spatial coherence from a high average power tabletop 46.9 nm laser was observed in two-pinhole interference experiments. Refractive anti-guiding and gain guiding along a capillary discharge-produced plasma column causes a rapid increase of the spatial coherence with amplifier length. Full spatial coherence was approached with a 36 cm long plasma of very high axial uniformity and a length to diameter ratio exceeding 1000: 1.born digitalarticleseng©2001 EDP Sciences.Copyright and other restrictions may apply.
