Theoretical and experimental results are presented for degenerate four-wave mixing In photorefractive KNSBN crystals. The angular dependence of transient- state and steady -state phase- conjugate reflectivities R in undoped and Pr -doped KNSBN have been measured respectively. Applied field dependence of phase - conjugate reflectivity in undoped KNSBN shows that transient-state R exceeds 260 and steady - state R can reach 122% at applied field E0 =5 kV/cm. By comparison ,Pr as a new impurity to provide a variety trapping centers in KNSBN crystals makes the response time about 3 times less. The probe intensity dependence of the response time and the steady phase- conjugate reflectivity in degenerate four -wave mixing within Cu-doped SBN is given.
