We show that the optical beam evolution equations at the interface between a metal and a biased centrosymmetric photorefractive (CP) crystal can exhibit delocalized surface waves, shock surface waves, and localized surface waves (LSWs). Only LSWs have not oscillating tails in the volume of the CP crystal. For a given value of the propagation constant b , the transverse width and energy of LSWs increases with the order of LSWs. For a given order of LSWs, the energy of LSWs decreases with an increase in |b||b|, the transverse width of LSWs increases with |b||b| when |b||b| is less than the absolute value of a certain threshold bctbct and decreases with an increase in |b||b| when |b|>|bct||b|>|bct|. The stability properties of these LSWs are also discussed in detail.
