| Outline of Final Research Achievements |
The purpose of this study is to develop a time-resolved ellipsometry technique using laser-driven plasma X-ray laser (XRL). It is necessary to measure accurately the beam intensity of the XRL beam with a large intensity fluctuation and then to analyze precisely the polarization state. In this study, the following has been developed: (1) two types of beam intensity monitors working at a wavelength of 13.9 nm based on a Mo/Si multilayer-coated photodiode and a molybdenum-overcoated diffraction grating; (2) soft X-ray ellipsometry with multilayer polarizing elements based on absolute reflectometry. The above is a basic technique for time-resolved ellipsometry that contributes to understand ultrashort pulse laser-materials interaction, such as laser-abration.
