Keywords:Nonlinear optics, Harmonic generation, Chiral media

We demonstrate the first generation of circularly-polarized high-harmonic radiation in solids using three-fold bi-chromatic driving fields. By matching the symmetry of the light polarization with the symmetries of the crystals, we study orientation-resolved, chiral electronic and magnetic properties in silicon dioxide (quartz) and on the surface of magnesium oxide (MgO), respectively.
