Abstract

Compact soft X-ray microscopes, using high harmonics as a light source, were constructed. A phase-reversal zone plate fabricated with polymethyl methacrylate was adopted to improve the focusing efficiency. Microscope images at 13 nm were acquired with sub-100 nm resolution, and the exposure time was reduced by a half, compared to that of the one using a gold Fresnel zone plate. A single-shot microscope image could be obtained using a strong harmonic at 22 nm generated in the two-color laser field consisting of the fundamental and the second harmonic of a femtosecond laser.
