We observed pronounced fringe visibility variations associated with microstructures in the beam's intensity profile. The transverse coherence length was measured to be about 1/20 of the beam diameter and did not significantly improve with longer plasma columns. The equivalent incoherent source size is determined to be 10 μm and the laser's peak spectral brightness ~ 3 × 1023 photons/sec/mm2/mrad2 within less than 0.01% spectral bandwidth.born digitalarticleseng©2006 Optical Society of America.Copyright and other restrictions may apply.
