中文摘要： 高能固体激光材料由于易产生自损伤，运行中的热管理等瓶颈问题，限制了它的使用频率、使用范围、运转周期和寿命。稀土配合物液体激光材料，其发光中心仍为稀土离子，有机溶剂为流动载体，溶剂对泵浦光和输出光无吸收，并且可以通过循环流动的方式进行热管理。因此，它兼具稀土固体激光材料优异的光学性能，又具有液体激光材料自修复和流动热管理的优点，为解决高能固体激光器的热管理瓶颈提供一种新的思路。本项目将研究稀土离子配位构型、有机配体声子振动对激光材料光学性能的影响规律，利用Judd-Oflet理论对材料的激光特性进行计算分析，设计制备具有高光化学稳定性、低吸收损耗、大受激发射截面、长荧光寿命的新型稀土配合物液体激光材料；建立新型液体激光增益介质的热管理模型，使其在有效热量管理条件下实现静态及动态激光输出，为探索发展新型激光器提供理论依据和技术参考。

英文摘要： There are some bottlenecks with high energy solid laser material such as: easily damaged, hot management in operation, which restrict its repeating frequency, the scope of use, operating cycle and lifetime. The rare-earth complex liquid laser material, its luminescent centers are still rare-earth ions, the flowing carrier is organic solvent which has no absorption with pumped and output laser. It can avoid the heat accumulation by cycle flowing. Accordingly, it combines the excellent spectra properties of rare-earth ions and good heat management of liquid, provides a new method for solving the heat management bottleneck of high energy solid laser material. In this project the effects of coordination configure and phonon vibration to optical properties of materials will be investigated, and the laser properties will be evaluated by Judd-Ofelt theory; the new rare-earth complex liquid laser materials with high actinic chemistry stable, low absorption loss, large emission cross-section, long lifetime will be designed and synthesized; the heat management model will be set, under the effective of heat management the stillness and continuous laser will be achieved; theoretical bases and technical references for exploring and developing new style laser system will be offered.
