水热法生长复合钛宝石激光晶体

Growth of Composite Sapphire/Ti:Sapphire by Hydrothermal Method

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.

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.
