▎ 摘  要

In order to develop the microscopic theory of the multiphoton interaction of graphene with strong laser fields of arbitrary polarization, the analytical solution of established evolutionary equation for graphene single-particle density matrix was obtained revealing the generalized Rabi oscillations of Fermi-Dirac sea in the graphene. Creation of coherent superposition states of the particle-hole pairs in the graphene at the multiphoton resonant excitation by laser pulses of arbitrary polarizations and harmonics generation at the particle-hole annihilation from these superposition states are shown.
