Abstract

Electric currents in condensed-matter systems driven by the intense laser fields are opening new frontiers in petahertz electronics. However, new challenges are arising as the role of band structure in solid-state high-order harmonic generation (SHHG) has yet to be resolved. Here, we adopt a derivative-free unconstrained optimization algorithm to optimize the band structure for the SHHG, and investigate the sensitivity of the SHHG to the band structure of the solid by using a single-band model. We find that the band structure play an important role in SHHG.
