Development of a compact polarization analysis apparatus for plasma soft X-ray laser

Imazono, Takashi; Koike, Masato

A laser-driven plasma soft X-ray laser (SXRL) system was constructed in Kansai Photon Science Institute. The SXRL having a 7-ps-duration pulse at a wavelength of 13.9 nm is generated from nickel-like silver plasmas generated by 10 J and ps-duration Nd:glass laser pulse. The polarization state of SXRL is considered to be almost vertically linearly polarized at the end station by the reflections of some Mo/Si multilayer mirrors installed in the SXRL beamline, but it has not been measured experimentally due to the lack of a polarization analysis apparatus. Therefore, we have developed a compact soft X-ray ellipsometer to be able to be installed in the SXRL beamline and evaluated the degree of linear polarization of SXRL with a Mo/Si multilayer polarizer whose polarization property has been characterized by using synchrotron radiation in advance.
