"plasma nonlinearities can be used to create efficient high-damage-threshold diffractive plasma lenses,” the researchers concluded. They said the simulations suggest that the intensity damage threshold of the lenses ranges from fluences of more than 1014 (100 trillion) watts per square centimeter (W/cm2) for the ionization mechanism to more than 1017 (100 quadrillion) W/cm2 ion-density mechanism... similar those that achieved experimentally plasma gratings... lens of this design may be feasible in the near future"
