Characteristics and discussion of self-pumped phase conjugation in a series of BaTiO[sub 3] crystals.

This letter presents the experimental results of self-pumped phase conjugation (SPPC) in barium titanate (BaTiO[sub 3]) crystals doped with Rh or Ce. It has been shown that the main parameters of SPPC depend very strongly on the concentration of dopants, the incident angles, and the cut type of the crystals. Some qualitative explanation of the experimental results are also given. © 2001 American Institute of Physics. [ABSTRACT FROM AUTHOR]
