设计并制备了一系列适用于超宽带拉曼放大的玻璃。除了带宽之外，这些玻璃的增益特性预期比基于二氧化硅的材料的增益特性高得多。从光纤制造的角度讨论了这些玻璃的热稳定性。解开了对整个拉曼谱带有贡献的各种结构单元。因此，以这样的方式定制各种带以获得宽的连续拉曼带。通过三次谐波测量研究了其非线性光学性质，这些性质对于光开关和其他非线性过程至关重要。
A family of glasses suitable for ultrabroadband Raman amplifications was designed and fabricated. In addition to the bandwidth the gain characteristics of these glasses are expected to be much higher than those of the silica based materials. The thermal stabilities of these glasses in view of fiber fabrication were discussed. The various structural units which contribute to the overall Raman band were unraveled. Accordingly the various bands were tailored in such a way to get a wide continuous Raman band. The nonlinear optical properties which are vital for optical switching and other nonlinear processes were studied via third-harmonic generation measurements.
