X‐ray laser formed from a gelatine– sandwich?
DOI: 10.1063/1.3071039
A group at the University of Utah believes they have made a hard x‐ray laser. The strikingly simple experiment was reported by John G. Kepros in a post‐deadline paper at the Third Rochester Conference on Coherence and Quantum Optics at the end of June. Subsequently Edward M. Eyring, F. William Cagle Jr and Kepros published a paper in the Proceedings of the National Academy of Sciences (69, 1744, 1972).
