Query: Tabletop single-shot extreme ultraviolet Fourier transform holography of
  an extended object   We demonstrate single and multi-shot Fourier transform holography with the
use of a tabletop extreme ultraviolet laser. The reference wave was produced by
a Fresnel zone plate with a central opening that allowed the incident beam to
illuminate the sample directly. The high reference wave intensity allows for
larger objects to be imaged compared to mask-based lensless Fourier transform
holography techniques. We obtain a spatial resolution of 169 nm from a single
laser pulse and a resolution of 128 nm from an accumulation of 20 laser pulses
for an object ~11x11{\mu}m 2 in size. This experiment utilized a tabletop
extreme ultraviolet laser that produces a highly coherent ~1.2 ns laser pulse
at 46.9 nm wavelength.
