We present a four-wave mixing (FWM) approach for generating structure light from a medium constituted of Landau level graphene when a magnetic field is present. A weak incident probing light beam is used for transitions within the Landau level and two strong electromagnetic fields are used for transitions at higher levels in our investigation of Landau levels. The excited state to ground state transition is coupled to the generated weak signal FWM field. In this investigation, we assume strong control fields to be structure lights and evaluate the absorption profile of generating field for numerous contexts of spatially structured electromagnetically induced transparency. For the FWM process, we demonstrate the intensity distribution of generated beams using the control beam’s orbital angular momentum.
