多芯光子晶体光纤便于与抽运激光器的大模场直径输出尾纤进行低损耗的熔接,能够把高功率的抽运激光耦合进光子晶体光纤中。同时,多芯光子晶体光纤的光场分布直径比单芯光子晶体光纤大,尽管激发非线性效应所需的激光抽运功率会有所提升,但是其激光损伤阈值也随之提升,即能够承受更高功率的抽运激光。因而,多芯光子晶体光纤非常适合用于构建全光纤化的高功率超连续谱光源系统。最近,国防科学技术大学采用高功率皮秒光纤激光抽运由光纤光缆制备技术国家重点实验室拉制 The multicore photonic crystal fiber facilitates low-loss fusion with the large-mode-field-diameter output pigtail of a pump laser and couples a high-power pump laser into the photonic crystal fiber. At the same time, the optical field distribution of multi-core photonic crystal fibers is larger than that of single-core photonic crystal fibers. Although the laser pumping power required to stimulate the nonlinear effect is improved, the laser damage threshold is also increased, which means it can withstand Higher power pumped laser. As a result, multicore photonic crystal fibers are well suited for the construction of all-fiber, high-power supercontinuum light source systems. Recently, the National Defense University of Science and Technology using high-power picosecond fiber laser pumping fiber optic cable preparation by the State Key Laboratory of drawing
