Paper Abstract

We demonstrated two high-throughput beam splitters for high-order harmonics in soft-x-ray region, an extremely-flat free-standing thin-film filter and a high-damage-threshold reflective beam splitter. The Al thin-film filter, which is coated with a SiC film to increase its oxidation tolerance, has a transmittance of 29% at 30 nm and the Si plate beam splitter set at Brewster's angle with respect to the pump wavelength has a reflectivity of 56% at 30 nm.
