| X-ray lasing is predicted to ensue when molecules are pumped into dissociative core-excited states by a free-electron-laser pulse. The lasing is due to the population inversion created in the neutral dissociation product, and the process features self-trapping of the X-ray pulse at the gain ridge. Simulations performed for the HCl molecule pumped at the 2p- 6s* resonance demonstrate that the scheme can be used to create ultrashort coherent X-ray pulses. |
