摘要
报道了一种新掺杂铌酸锂晶体Ｚｎ∶Ｆｅ∶ＬｉＮｂＯ３，它具有优良的光折变四波混频性能，位相共轭反射率可达１００％。且与Ｆｅ∶ＬｉＮｂＯ３相比，抗光散射能力强，响应速度快。本文通过对高掺ＺｎＯ后晶体的抗光损伤能力和光电导值的测试分析，讨论了Ｚｎ∶Ｆｅ∶ＬｉＮｂＯ３晶体抗光散射和响应速度提高的机理。
A new doped Zn∶Fe∶LiNbO 3 crystal with photorefractive four wave mixing properties is reported in this paper. The phase conjugate reflectivity can be up to 100%. Its resistance of light induced scattering is increased and the response is improved comparing with that of Fe∶LiNbO 3. The machenism of such enhancements is discussed by measuring the photoconductivity of the crystals and analysizing the optical damage resistant of heavy doped Zn∶LiNbO 3.
