We report the demonstration of an amplitude-division soft-x-ray interferometer that can be used to generate high-contrast interferograms at the wavelength of any of the saturated soft-x-ray lasers (5.6–46.9 nm) that are available at present. The interferometer, which utilizes grazing-incidence diffraction gratings as beam splitters in a modified Mach–Zehnder configuration, was used in combination with a tabletop 46.9-nm laser to probe a large-scale (∼2.7-mm-long) laser-created plasma.
