## Description

- description: High harmonic generation (HHG) in solid-state materials is an emerging
    field of photonics research that can unveil the detailed electronic structure
    of materials, bond strengths and scattering processes of electrons. Although HHGin
    semiconducting and insulating materials has been intensively investigated both
    experimentally and theoretically, metals have rarely been explored because the
    strong screening effect of high-density free electrons is considered to significantly
    weaken the HHG signal. Here, we investigated HHG upon infrared excitation in bulk
    hexagonal metal titanium (Ti), a typical building block for practical lightweight
    structural materials. By analyzing the polarization dependence, the approach revealed
    the three-dimensional (3D) anisotropy in the electronic states. The results demonstrated
    the potential of HHG spectroscopy for characterizing 3D bonding anisotropy in
    metallic systems that are of fundamental importance for designing lightweight
    and strong structural materials.
