晶体/玻璃复合激光介质材料的结构设计和可控制备研究

随着全固态、高功率、短脉冲激光技术的发展，激光材料也迎来了新的发展机遇。在分析比较了单晶、玻璃和透明陶瓷的性能特点后，本项目拟在具有简单立方结构的碱土金属氟化物晶体（MeF2，Me＝Ca, Sr, Ba）中，实现Yb3+的局域配位结构的设计与调控，研制出具有宽光谱、高增益的Yb:MeF2体单晶。在此基础上，结合晶体、玻璃、透明陶瓷在性能和制备方式上的各自优点，融合流体激光器的部分设计思想，原创性地提出功能组装型的晶体/玻璃复合激光材料的设计思想和技术方案，研制出一类具有宽光谱、高增益、可大尺寸制备等特性的新型晶体/玻璃复合激光材料，并实现在超短脉冲激光领域的新应用。

With the development of all-solid-state, high-power, and short-pulse width lasers, laser materials have new developing opportunities. After the analysis and comparison of the performance characteristics of the single crystal, glass and transparent ceramics, the first intended job is to use simple cubic structure of the alkaline earth metal fluoride crystals (MeF2, Me = Ca, Sr, Ba) to achieve Yb3+ local coordination structure design and regulation, and to develop a wide spectrum, high gain Yb:MeF2 single crystal. On this basis, combining the respective advantages of crystal, glass, transparent ceramics in the way of performance and preparation, and integration of the part of the fluid laser’s design ideas, it is originally proposed the design idea and technical solution of functional assembly crystal / glass composite laser material, and then to develop a class of new crystal / glass composite laser materials with a wide spectrum, high gain, large size and other characteristics, and to explore new applications in the field of ultrafast laser.
