Electron band structure detection by high-order optical harmonic generation in solids

详细

We show that the full electron band structure of solids can be determined by means of high-order harmonic generation using ultrashort laser pulses in the mid-infrared range. Electron and hole wave packets whose direction of motion is controlled by the polarization of laser pulse relative to the symmetry axes of the Brillouin zone are shown to provide an effective probe for the electron
