It is well known that the interaction of laser beams with periodically corrugated surfaces (e.g., with diffraction gratings) can have a resonant character and can be accompanied by the strong local field's enhancement, suppression of the specular ref

Publikováno v: SPIE Proceedings.

The x ray emission from femtosecond laser-driven plasma has been investigated using spherical multilayered mirrors. Different laser pulse widths have been used. The conditions required to produce high intensity x ray emission (up to 1011 W cm-2) from
