Single-shot picosecond resolution Fourier transform holographic microscopy with large field of view using a compact soft X-ray laser

摘要

We demonstrate single-shot Fourier transform holography with a 7 μm diameter field of view and picosecond time resolution using a highly coherent ～5 ps pulse duration tabletop Ni-like molybdenum soft X-ray laser at 18.9 nm wavelength. The essentially full spatial coherence soft X-ray source with close to diffraction-limited divergence was implemented utilizing a dual-plasma amplifier scheme. The high flux illumination of～ 2×10~(11) photons per pulse was split using a Fresnel zone plate to generate the object and reference beams creating high contrast Fourier transform holograms. The final image was numerically reconstructed by 2D Fourier transform. A minimum half-pitch spatial resolution of 62 nm was obtained.
