摘要/Abstract

摘要： 水热法生长了复合钛宝石(Al₂O₃/Ti:Al₂O₃)激光晶体.对外层Al₂O₃X射线ω扫描表明其晶体质量很高.外层生长的Al₂O₃和内部的钛宝石激光棒结合牢固、紧密,因而能适应高强度泵浦所带来的激光介质内部的热应力.复合激光晶体界面层带来的光损耗很小.就我们所知,这是首次用水热法生长复合激光晶体.

Abstract: Composite sapphire/Ti:sapphire crystals for high power applications were grown by the hydrothermal method. The X-ray diffraction pattern of omega scan indicates that the coating Al₂O₃ is of high quality. The strong bonding between the coating Al₂O₃ and Ti:Al₂O₃ is suitable for the strong thermal stresses present with intense pumping. The optical loss at the boundary of the composite crystal is considerably low.

Key words: laser materials, laser cooling, optical materials, Ti:sapphire
