Abstract
Coupling of a soft X-ray laser beam with a relaying concave mirror in a sequentially pumped amplifier geometry using the Ne-like Ge system h as been studied experimentally. Preliminary observations indicate an i ncrease in the spatial coherence of the amplified relayed beam. In add ition, near-field imaging of one of the amplifier plasmas shows a doub le-lobed intensity pattern of the emergent beam indicating refractive guiding of the amplified beam with components both normal and tangenti al to the target surface.
