High contract femtosecond laser-driven intense hard X-ray source for imaging application |

| Abstract: |
In this report we address the current situation of laser-driven hard X-ray sources for imaging applications,especially the saturation of X-ray conversion efficiency and the serious impact upon imaging quality.By employing high contrast laser pulses,the conversion efficiency to X-rays from solid foil targets is improved and the structure of the spectrum can be optimized with respect to imaging applications.In addition,bright ArK-shell X-rays with very little continuum background have been generated by irradiating,with an ultra-high contrast laser,a target of Ar gas clusters created by a gas jet. These improvements show great potential for single-shot ultra fast X-ray imaging. |
