| 摘 要： | BaWO4晶体是一种很有应用前景的喇曼激光晶体。本文根据对称性分类,用商群理论分析了Ba-WO4晶体的喇曼光谱。一个原胞中含有两个BaWO4分子,理论上有36个振动膜,和我们用群论计算得数目一致。其中有18支拉曼活性光学膜。我们测得了10支拉曼峰,并对测得的各个配置的拉曼峰进行了指认,其中X(ZZ)X配置921cm-1处的喇曼峰强度最强,线宽较窄,对于作为喇曼激光晶体来讲是很有益的。 |

| Abstract: | In this paper Raman spectra of BaWO_4 crystal was analyzed in terms of group space theory.Thirty-six vibration modes were acquired.The primitive cell contains two formula units in BaWO_4 crystal.Therefore,it has thirty-six free degrees.The number of vibration modes is complied with that of the free degree. It was analyzed that BaWO_4 crystal has eighteen Raman-active optical spectra. It was acquired 10 Raman peaks from our experiment,and we analyzed one by one.It is found that at 921cm~(-1),it has the strongest intensity and narrow bandwidth with the scattering configurations of X(ZZ)X.Therefore it is suitable for BaWO_4 crystal as the Raman laser crystal. |
