Abstract

In this paper, we review the optimization and characterization of a high-order harmonic generation (HHG) source for application in coherence imaging, and the use of this light source in a digital in-line holography setup. The high-order harmonic beam is generated by focusing a powerful infrared beam into an Ar gas cell. The length of the cell and the focusing parameters are optimized to maximize the HHG output. By spectrally filtering and focusing the generated harmonic beam and positioning a 2D detector, we obtain a table-top light source suitable for in-line holography, capable of recording a hologram with a single 40 fs XUV pulse. The reconstructed images have a spatial resolution in the micrometer range.
