中文摘要：
合成 Nd : 有 undoped 钇铝柘榴石结束帽子的钇铝柘榴石水晶被热结合制作技术。结合的接口的宽度是大约 0.5 渭 m 的扫描电子显微镜学(SEM ) 结果表演。激光 micro-Raman 被用来学习合成水晶的结合的接口。拉曼系列和结合的接口图象的结果显示 undoped 钇铝柘榴石和 Nd : 钇铝柘榴石晶体很好一起被结合了。而且，结构和结合的接口的作文与 undoped 钇铝柘榴石水晶一样，这能被拉，并且 Nd3+ 离子不进入结合的接口和 YAG 方面。这个性质是有益的减少 boned 接口并且到的热效果改进激光稳定性。CLC 数字 O782 - O731 由中国的国家自然科学基础支持了(号码 60478025； 50472104 )
英文摘要：
The composite Nd：YAG crystal with undoped YAG end caps was fabricated by thermal bonding technique. Scanning electron microscopy （SEM） result shows that the width of the bonded interface was about 0.5 lain. The laser micro-Raman was used to study the bonded interface of the composite crystal. The results of Raman spectra and the bonded interface image indicate that the undoped YAG and Nd：YAG crystals have been well bonded together. Furthermore, it can be drawn that the structure and the composition of the bonded interface are the same as the undoped YAG crystal, and that the Nd^3＋ ions do not enter the bonded interface and the YAG side. This property is advantageous to decrease the thermal effect of the boned interface and to improve the laser stability.
