摘要/Abstract

摘要： 采用群论的方法分析了BaWO4晶体的对称性分类，得到36个简正模，与BaWO4晶体的运动自由度相等，其中有18支喇曼活性光学膜. 实验中，采用X(ZZ)，X(YY)，Z(XY)和X(YZ)配置获得了Ag, Ag＋Bg, Bg, Eg振动模，共观测到10支喇曼峰，并对观测到的各个配置的喇曼峰进行了指认，其中X(ZZ)配置的921?cm-1（υ1）处的喇曼峰强度最强，频移最大，线宽较窄，容易获得较高的喇曼增益，是喇曼激光器设计中的首选谱线，为喇曼激光器的设计提供了理论指导.

Abstract: BaWO4 crystal is proposed to be a prosperous Raman crystal. Raman spectra of BaWO4 crystal was analyzed in terms of group space theory. Thirtysix vibration modes are acquired. The number of vibration modes is agree with the free degree of BaWO4 crystal. The results show that BaWO4 crystal has eighteen Ramanactive optical spectra. Ten Raman peaks were acquired and assigned one by one. It is found that spectrum of 921?cm-1（υ1） has the strongest intensity and largest Raman shift with the scattering configurations X(ZZ). It is the most suitable spectrum for Raman lasers.
