摘要

实验研究了λ = 0.63 μm (He-Ne激光)下，差频光束(Ω = Ω 1 ~ Ω 2 = 2π 50 Hz)在交变外场E0 cos(Ωt)下在未掺杂的Ba2NaNb5O15晶体中形成静态全息图。研究了衍射效率与光栅空间频率的关系。考虑到二次光栅的影响，定性结果与理论结果一致。

Nondegenerate two-wave interaction in a barium sodium niobate crystal

An experimental investigation was made of the formation of a static hologram by difference-frequency beams (Ω = ω1 – ω2 = 2π 50 Hz) in an alternating external field E0 cos(Ωt) in an undoped Ba2NaNb5O15 crystal at λ = 0.63 μm (He–Ne laser). The dependence of the diffraction efficiency on the spatial frequency of the grating was studied. A qualitative agreement was achieved with theoretical results allowing for the influence of a secondary grating.
