Exprimental results of induced self pumped phase conjugation (ISPPC) by an incoherent beam in photorefractive (BaSr)TiO3 crystal are reported. It is found that the features of ISPPC output depend not only on the parameters of signal beam but also the intensity of induced beam. Optical bistability of ISPPC output is observed under certains conditions. The effects observed are attributed to the local modification of the Fanning geometry of the signal beam by induced beam.
