摘要

Photoinduced light scattering (PILS) in nominally undoped LiNbO_3 with the mixed photovoltaic and diffusion charge transports is studied theoretically and experimentally. All parameters describing the holographic behavior of LiNbO_3 are received from the angular distribution of the scattering intensity: gain factor Γ, diffusion field E_D, photovoltaic field E_(pv), and frequency detuning Ωτ_(di). The technical advantage of this PILS method is the low requirement of mechanical stability.
