Outline of Final Research Achievements |
To realize a diffraction limited focusing of an attosecond pulse by using the Schwarzschild optical system, we developed a multilayer mirror at the 40 nm XUV region and realized a SiC/Mg multilayer mirror with the maximum reflectivity of 38%. The reflection bandwidth of our mirror can cover the pulse duration of 500 as or less. We successfully fabricated a suitable multilayer mirror, which can be used for focusing of an attosccond pulse. We also developed a high power driver laser for generating GW-scale attosecond soft x-ray pulses.
