Abstract
We investigate the anisotropy of high-harmonic generation (HHG) in zinc selenide (ZnSe) under varying mid-infrared laser intensities. Even and odd harmonics show out of phase rotational dependence, with even orders exhibiting greater consistency. The shift in angular dependence with increasing intensity indicates interband and intraband interplay and the influence of ZnSe’s anisotropic band structure. These findings highlight how crystal symmetry and electronic anisotropy shape intensity dependent solid-state HHG dynamics.

Madison completed a Bachelor's degree in Physics at Imperial College London, where an early interest in laser physics led to a summer research placement at DESY, working on mode locking in fibre lasers. Building on this foundation, she went on to earn a Master’s degree in Optics and Photonics, also at Imperial College. Madison is now continuing at Imperial, pursuing a PhD in laser physics, focusing on high harmonic generation in solids, with particular emphasis on the anisotropy effects in these processes.
