Abstract
The crystal harmonic spectra of MgO from an ultrashort midinfrared laser pulse are shown to exhibit the Cooper minimum characteristic. This study could potentially be useful for retrieving the band information of solid materials and all-optical reconstruction of the band structure through high-order harmonic generation.
