FIG. 1.

Spectral tailoring: spectral characteristics of the harmonic beam depending on the macroscopic phase-matching parameters. Top (bottom) three curves: variation in the focal point position inside the gas cell z (pressure P) with constant pressure P (constant focal point position z). Global intensity maximum is at . The laser focus is close to the exit plane and deeper inside the gas cell for larger values of z for the position of maximum flux.

High-dynamic range diffraction images of the sample in Fig. 3: an image (a) of low-angle diffraction pattern and images [(b) and (c)] of high-angle diffraction patterns are acquired and stitched together to form a single image (d).

Microscopic periodic sample: scanning electron microscopy image (a), reconstructed image (b), diffraction pattern (c), and zoom into low-diffraction angle and high-diffraction angle regions [(d) and (e)].

Microscopic aperiodic sample: scanning electron microscopy image (a), reconstructed image (b), diffraction pattern (c), and zoom into low-diffraction angle and high-diffraction angle regions [(d) and (e)].

FIG. 5.

Macroscopic sample: carbon film mounted in a sandwich structure (a); copper support grid of the nanometer-carbon film (b), and carbon film mounted on that grid (c); diameter pinhole to confine the area of illumination (d).

FIG. 6.

Distortions in the diffraction images: complex structure of the mounted pinhole on both sides (a); diffraction pattern of the pinhole itself (b); harmonic beam illuminates the pinhole first, then carbon film (c); and harmonic beam illuminates the carbon film first, then the pinhole (d).
