Figures & Tables
Fig. 1. (a) Schematic overview of the experiment setup. L–N means the laser is interacting with the nanowire structure directly. L–S means the laser is interacting with the substrate; (b) scanning electron microscopy image of the nanowire array target.
Fig. 2. (a) Spectrum of K-shell lines obtained for 94.8 J laser incidence on the target with 20 μm nanowires; (b) dependence of the total count of K α on the laser energy for the target with 20 μm nanowires.
Fig. 3. (a) Original K α image for a nanowire array target with 10 μm long nanowires and a 5 μm thick substrate. Corresponding laser peak intensity is 1 × 10 19 W / cm 2 ; (b) restored image from (a).
