Polarization Flipping of Even-Order Harmonics in Monolayer Transition-Metal Dichalcogenides

Table 1

Symmetry restrictions for the HHG response of monolayer TMDCs along the high-symmetry axes. The directions of the MIR field ( or ) are referenced to the crystal mirror planes, and the directions of the high harmonics ( or ) are referenced to the MIR field. Odd-order harmonics are restricted to along the MIR field direction, whereas the even-order harmonics can be produced either parallel or perpendicular to the MIR field.
