| Abstract: | It is shown that temporal broadening of an X-ray femtosecond pulse under propagation through a tapered nanometer-scale waveguide is negligible small for the wide region of the guide and pulse parameters. The output pulse has the step-like transverse intensity distribution. The conventional waveguide theories do not predict this phenomenon. |
