Abstract

An efficient CW bismuth fiber laser operating around 1.46 μm with an efficiency of >50% and an output power of >20 W has been developed on a bismuth-doped GeO(2)-SiO(2) fiber. The laser demonstrates weak dependence of the output power on temperature in comparison with bismuth lasers operating near 1.15 and 1.3 μm. The laser generation has been obtained in the range 1.39 to 1.54 μm. The first linearly polarized bismuth-doped fiber laser at 1.46 μm based on a PANDA-type fiber has been demonstrated.

摘要

已在掺铋 GeO(2)-SiO(2)光纤上研制出一种高效的 CW 掺铋光纤激光器，其工作波长约为 1.46 μm，效率>50%，输出功率>20 W。与工作在 1.15 和 1.3 μm 附近的掺铋激光器相比，该激光器的输出功率对温度的依赖性较弱。激光产生范围为 1.39 至 1.54 μm。基于 PANDA 型光纤，已演示了首个 1.46 μm 的线偏振掺铋光纤激光器。
