We investigate the electron state in an armchair graphene nanoribbon exposed to the time-periodic strong electric field of intense light wave and constant in time weak electric field both polarized to the ribbon axis. The Dirac approach is taken for the investigation of the electron transitions between the size quantized electron and hole subbands. It is shown that the probability of an intersubband multiphoton transition, calculated in the resonant approximation, oscillates in time with the Rabi frequency, which in turn depends on the ribbon parameters and strong periodic electric field magnitude. The oscillations' magnitude is modified significantly by the weak electric field both, below and above the frequency threshold (Franz-Keldysh effect). Keywords: graphene, ribbon, Franz-Keldysh effect.
