We have investigated the oscillatory behavior of diffraction efficiency under ultraviolet-light-recoring experimentally and theoretically. We utilized a model in which electrons and holes can be excited from impurity centers in the ultraviolet region to study the oscillatory behavior of the diffraction efficiency. On the basis of the material equations and the coupled-wave equations, we found that the oscillating behavior is due to the oscillation of the relative spatial shift, not the large space-charge field. And the electron-hole competition may cause the oscillating behavior of spatial phase shift ? and the reduction of space-charge field Esc.
