Dissociative x-ray lasing.
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(1/2)→6σ resonance demonstrate that the scheme can be used to create ultrashort coherent x-ray pulses.
