We demonstrate the generation of a highly polarized soft-x-ray beam with a compact high-repetition-rate tabletop soft-x-ray laser. The radiation emitted by a high-average-power discharge-pumped tabletop Ne-like Ar soft-x-ray laser operating at 46.9 nm was polarized with a pair of Si/Sc multilayer mirrors designed for 45° operation. A degree of polarization greater than 0.96 was obtained. The polarized beam was used to characterize the efficiency of a diffraction grating. Intense polarized soft-x-ray radiation generated by compact tabletop sources has the potential to affect numerous other applications.
