Growth and Optical Absorption Spectra of Nd3+ Doped Sr3Ga2Ge4O14 Crystals

采用坩埚下降法生长了Nd3+掺杂浓度分别为15%、8%和2.5%原子分数的Sr3Ga2Ge4O14晶体,所得晶体最大尺寸为φ26mm×15mm.Nd3+掺杂Sr3Ga2Ge4O14晶体的特征吸收峰波长为806nm,与Nd3+离子在YAG中的特征吸收峰相比,向短波方向发生了微小的偏离.这是Sr3Ga2Ge4O14晶格中Ga3+和Ge4+的统计分布所致.Nd3+:SGG晶体的这些特性将有助于泵浦效率的提高和泵浦阈值的降低,因此Nd3+:SGG晶体有望成为一种新型的LD泵浦固体激光材料.
