We find the exact solution of graphene carriers dynamics under electromagnetic radiation. To obtain the solution of the corresponding Dirac equation, we combine Floquet theory with a trial solution. Then the energy spectrum is obtained without using any approximation. We also prove that the energy spectrum presents a gap opening, which depends on the radiation frequency and electric wave intensity, whereas the current shows a strongly nonlinear behavior.
