| 中文摘要 | The scheme of x ray generation by the interaction of ultra-short intense laser puls with two thin solid foils is re-investigated by one-dimensional numerical simulation. Attention is paid particularly to the effects of the thickness and the density distribution of the source target on the frequency spectrum and the conversion efficiency of the produced x ray emission, where the source target provides a relativistic electron layer. When the thickness of the source target is comparable to or smaller than the wavelength of x ray lambda/4 gamma(2)(x) (lambda is the wavelength of the incident laser), quasi-monochromatic x ray spectrum can be generated. Otherwise the spectrum will be broadened significantly and the maximum frequency will decrease rapidly. In addition, the presence of inhomogeneous preplasma in front of the foil will induce a similar change of the spectrum. |
