    Higher-order anisotropic self-diffraction up to third orders have been observed in Cerium doped barium titanate by using red beam at 633 nm from He-Ne laser. In our experiment, the third orders and second orders have been observed simultaneously for the first time from our knowledge. From our observation, the phase conjugate beam has not been generated before and after the appearance of higher orders as observing when the green beam from the Argon-ion laser at 514.5 nm has been used. The diffraction efficiency and the decay rate of the grating have been measured as well in the red light case. © 2012 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE).
