采用自制的碲酸盐微结构光纤作为非线性介质, 利用实验室自己搭建的1 560 nm飞秒光纤激光器作为泵浦源, 研究了泵浦功率、光纤长度、非线性系数和群速度色散对超连续谱展宽的影响, 并通过优化碲酸盐微结构光纤的结构获得了覆盖1 300~2 200 nm的全光纤超连续光源。

Supercontinuum generation in homemade tellurite microstructured fibers by using a homemade 1 560 nm femtosecond fiber laser as pump source was demonstrated. The effects of the pump power, the length of fiber, the nonlinear coefficient and group velocity dispersion on the supercontinuum generation were investigated in detail. By optimizing the fiber structure, we archived an all-fiber supercontinuum source covering the range from 1 300 to 2 200 nm.
