Resumen

We report the simultaneous lasing of two distinct K α emissions at photon energies of 7.48 keV (Ni K α 1 ) and 8.05 keV (Cu K α 1 ). This was achieved by a population inversion induced through intense X-ray free-electron laser (XFEL) irradiation of a Cu–Ni alloy foil. This demonstration of multi-color X-ray lasing using a single XFEL source is expected to contribute significantly to the future development of X-ray lasers and their applications.
