Abstract
Non-steady-state photocurrents are generated in reduced iron-doped lithium niobate crystals. Dependences on spatial frequency and on modulation amplit ude are well described by the existing theory and a Debye screening length of 19 nm is determined. The non-steady-state photocurrents strongly decreas e for frequencies above 2 Hz. The technique might be useful for material ch aracterization and for convenient active stabilization of holographic setup s against mechanical vibrations. (C) 1999 American Institute of Physics.
