  We investigate theoretically the transmission of electrons through a pair of
{\delta}- function magnetic barriers in graphene in presence of external
monochromatic, linearly polarised and CW laser field. The transmission
coefficients are calculated in the framework of non-perturbative Floquet theory
using the transfer matrix method. It is noted that the usual Fabry-Perot
oscillations in transmission through the graphene magnetic barriers with larger
inter barrier separation takes the shape of beating oscillations in presence of
the external laser field. The laser assisted transmission spectra are also
found to exhibit the characteristic Fano resonances (FR) for smaller values of
the inter barrier separation. The appearance of the perfect node in the beating
oscillation and the asymmetric Fano line shape can be controlled by varying the
intensity of the laser field. The above features could provide some useful and
potential information about the light - matter interactions and may be utilized
in the graphene based optoelectronic device applications.
