We demonstrate Brillouin lasing in a single-mode TeO(2)-Bi(2)O(3)-ZnO-Na(2)O tellurite fiber. A peak value of Brillouin gain coefficients of 1.6989 x 10(-10) m/W is measured on the basis of gain characteristics. An all-fiber Brillouin laser with a maximum unsaturated power of 54.6 mW at 1550 nm and a slope efficiency of 38.2% are achieved from a 200 m tellurite fiber by employing a ring cavity. In addition, a tunable Brillouin comb tellurite fiber laser is demonstrated.
我们在单模碲酸铋（TeO₂）-氧化铋（Bi₂O₃）-氧化锌（ZnO）-氧化钠（Na₂O）碲酸盐光纤中实现了布里渊激光发射。基于增益特性测量得到布里渊增益系数的峰值为1.6989×10⁻¹⁰ m/W。通过采用环形腔，在一根200 m长的碲酸盐光纤中实现了全光纤布里渊激光器，其在1550 nm处的最大不饱和功率为54.6 mW，斜率效率为38.2%。此外，还展示了一种可调谐布里渊梳状碲酸盐光纤激光器。
