Optics letters, 1991•opg.optica.orgThe photorefractive recording process as described by Kukhtarev's material equations is
investigated for large modulation depths. We find that for modulation 1 the density ND+ of
ionized traps at the dark sites is zero in the steady state if dark conductivity can be
neglected. Therefore, in this case, it is essential to take the depletion of ionized traps into
account.
