Generation of attosecond pulses in “water window” range by a plasma-based X-ray laser

Abstract

SynopsisWe suggest a technique to generate a train of attosecond pulses in “water window” range by hydrogen-like C5+ plasma-based X-ray laser with two sequentical active plasma channels irradiated by two different optical laser fields with orthogonal polarizations. We show also the possibility to transform the radiation of a plasma-based X-ray laser dressed by an optical laser field into a train of attosecond pulses in a resonant absorber irradiated by the different optical field.
