In the lecture, Professor Zhang Qin Yuan delved into the critical role of rare-earth-doped laser glass as a key gain medium in high-energy laser fusion systems, high-power fiber lasers, and optical communication networks. He pointed out that current theoretical frameworks have limitations in explaining complex spectral behaviors and establishing reliable quantitative composition-structure-property (C-S-P) relationships. Traditional methods rely heavily on extensive trial-and-error experiments, which are costly and provide limited scientific insight. Professor Zhang proposed a phase diagram-based eutectic compound approach, systematically elucidating the C-S-P relationships in various laser glasses. He also explored the synergistic integration of this approach with emerging computational technologies such as machine learning and molecular dynamics simulations, thereby establishing a comprehensive multi-scale C-S-P prediction framework. Concluding the lecture, Professor Zhang commented on the current progress and challenges in the quantitative prediction of C-S-P relationships and offered a forward-looking perspective on future development directions.
