稀土晶体及其制备工艺研究进展

Research progress of rare earth crystal and its preparation technology

稀土晶体材料由于其独特的磁学、光学等特性,广泛应用于光纤通讯、电子信息、航空航天、半导体、国防安全等领域。本文综述了坩埚下降法、提拉法、温度梯度法三种应用最为广泛的稀土激光晶体材料制备工艺国内最新研究进展,为稀土晶体材料的进一步研究提供了参考。

Rare earth crystal materials are widely used in optical fiber communication,electronic information,aerospace,semiconductor,national defense and security and other fields due to their unique magnetic and optical properties.In this paper,the latest research progress of the three most widely used preparation processes of rare earth laser crystal materials,i.e.crucible descent method,Czochralski method and temperature gradient method,is reviewed,which provides a reference for the further research of rare earth laser crystal materials.
