抄録
<jats:p>The authors use Fresnel diffraction from knife-edges to demonstrate the spatial coherence of a tabletop ultrafast x-ray source produced by laser-plasma interaction. Spatial coherence is achieved in the far field by producing micrometer-scale x-ray spot dimensions. The results show an x-ray source size of 6μm that leads to a transversal coherence length of 20μm at a distance of 60cm from the source. Moreover, they show that the source size is limited by the spatial spread of the absorbed laser energy.</jats:p>
