Description
Since the advent of x-ray free-electron lasers (XFELs), considerable
efforts have been devoted to achieve x-ray pulses with better
temporal coherence. Here, we put forward a scheme to generate
fully coherent x-ray lasers (XRLs) based on population inversion in
highly charged ions, created by fast inner-shell photoionization
using XFEL pulses in a laser-produced plasma. Numerical simulations
show that one can obtain high-intensity, femtosecond x-ray pulses
of relative bandwidths $Δω/ω=10^{-5} ~ 10^{-7}$ by orders of magnitude
narrower than in XFEL pulses for discrete wavelengths down to the
sub-ångström regime.
