We study the transport properties of Dirac fermions through gapped graphenethrough a magnetic barrier irradiated by a laser field oscillating in time. Weuse Floquet theory and the solution of Weber's differential equation todetermine the energy spectrum corresponding to the three regions composing thesystem. The boundary conditions and the transfer matrix approach {are} employedto explicitly determine the transmission probabilities for multi-energy bandsand the associated conductance. As an illustration, we focus only on the threefirst bands: the central band $T_0$ (zero photon exchange) and the two firstside bands $T_{\pm1}$ (photon emission or absorption). It is found that thelaser field activates the process of translation through photon exchange.Furthermore, we show that varying the incident angle and energy gap stronglyaffects the transmission process. The conductance increases when the number ofelectrons that cross the barrier increases, namely when there is a significanttransmission.
