Combined, table-top extreme-ultraviolet ellipsometry and polarimetry for studying ultrafast processes in matter
Abstract We demonstrate the characterization of the complete polarization state of broadband extreme-ultraviolet radiation produced via high-harmonic generation in a gas target, measured with a double-stage polarimeter and a reaction microscope. The ellipsometric parameters of the reflective optics used in the polarimeter—meaning the extinction ratios and phase shift—were determined simultaneously. The results serve as a basis for table-top extreme-ultraviolet polarimetric and ellipsometric measurements, allowing ultrafast studies of polarization-sensitive matter, which require exact knowledge of the polarization state of the ionizing radiation.
