Study on Self-Built Optical Path Production in Ce-Doped BaTiO3Stimulated Photorefractive Scattering Self-Pumped Phase Conjugator

The observations on the stimulated photorefractive scattering self-pumped phase conjugator (SPS-SPPC) in Ce-doped BaTiO3 demonstrate that the self-built pumped paths in the SPS-SPPC are induced by the scattering seeds. Using these results, a formation mechanism of the SPS-SPCC is presented, which is related to the scattering seeds, contradirectional two-wave mixing and four-wave mixing. The production conditions and characteristices of the pumped paths are given. It shows that the large backscattering coefficient is always advantageous to the production of these paths. The maximum of the phase conjugition reflectivity attains 80%.
