Popis: We introduce and demonstrate a conceptually new manifestation of the Berry phase in light-driven crystals. We then experimentally demonstrate this phase by using a strong laser field to engineer an internal interferometer, induced during less than one cycle of the driving field, which maps the phase onto the emission of high-order harmonics.
