| 摘 要： | 继文献1]之后,我们又研究了掺Fe浓度为0.07％的LiNbO3:Fe晶体的光折变对喇曼光谱的影响。发现在x(zx)z和y(zy)z配置下出现异常。这可以由异常声子的极化电场与光折变在晶体中形成的强空间电荷场的相互作用来解释。

| Abstract: | Following our previous work 1], the influence of photo-induced refractive index change on Raman spectra of LiNbO3 crystals doped with 0.07% Fe has been further studied. Anomalous phenomenon appeared in x(zx)z and y(zy)z geometry. This can be explained as the result of interaction between the polarization electrical field of extraordinary phonon and the strong space charge field forming after photo-induced refractive index change in the crystals. |
