Fluorescence imaging of nonlinear x-ray propagation and lasing

Physical Review Research
We introduce a general approach for probing nonlinear x-ray propagation by imaging secondary fluorescence emitted transverse to the driving field. When a short, intense x-ray pulse excites a deep 1s core orbital, subsequent Kα emission from spin-orbit ...
