研究了掺铁铌酸锂晶体中会聚光束的后向散射。由于晶体的非线性特性，后向散射表现出暂时波动的斑点，在某些情况下，这些斑点会过渡到入射光束的相位共轭。我们的观察似乎指向了光折变介质中一种新的自抽运相位共轭。
We investigate the backscattering for converging beams in iron-doped lithium niobate crystals. Due to the nonlinear properties of the crystal, backscattering exhibits temporally fluctuating speckles that make a transition to the phase conjugate of the incident beam under certain circumstances. Our observation seems to point to a new kind of self-pumped phase conjugation in photorefractive media.
