In a biased photorefractive crystal, the process of two one-dimensional waves mixing, i.e., the dynamical evolution of both pump beam and signal beam, is traced by numerically solving the coupled-wave equation. Direct simulations show that the propagation and stability of the two beams are completely determined by the system parameters, such as the external bias field, the intensity and the beam waist of the pump beam. By adjusting these parameters, one can control the state of two Gaussian waves mixing. The numerical results are helpful for performing a two-wave mixing experiment.

Bi 12 TiO 20 (BTO)crystals have same structure as that of the Bi 12 SiO 20 (BSO)which is one of the most popular photorefractive *** both of them belong to cubic non centrosymmetric nonferroelectric *** cubic nonferroelectric oxides exhibit a number of advantages such as higher sensitivity and faster respond for applications in *** to BSO,BTO have the largest electro optical coefficient and lower optical activity,especially it exhibits much high photosensitivity in the red light region that permits to use a cheap He Ne *** is,therefore,of high potential for applications in optical devices.
