Abstract

We describe the use of a dispersive Young's slits coherence diagnostic for determining the transverse coherence length of a soft x-ray laser source. W have studied the emission from the Ne-like germanium x-ray lasing lines at 23.2/23.6 nm for comparison with the 19.6 nm lasing line obtained with the use of a prepulse. The effective source size has been determined for both these output modes from the calculated coherence length. We conclude that the use of a prepulse leads to a significant reduction in effective source size at 19.6 nm.
