The self-pumped phase conjugation in CSBN75 is studied in this investigation basing on an anti- traditional method, which using part laser spot to irradiate crystal. With the change of the spot size projected on the crystal, the deformed laser spot that introduced by self-pumped phase conjugation and its complementary pattern are distinctly displayed on the screen. Tentative analysis is executed in this paper. However, it will be applied in optical information processing with these crystals.
