摘要

摘要:
在高功率光纤激光系统中，包层光滤除器能将光纤中包层光滤除以保证输出激光光束质量，光纤端帽通过对输出激光扩束降低输出光纤端面的光功率密度，从而保护光纤端面不受损坏，两者都是高功率光纤激光系统稳定运行的重要核心器件。将包层光滤除器和光纤端帽进行一体化设计，制备了一体化高功率光纤包层光滤除器和光纤端帽并分别应用于20 kW合束系统和单纤系统中，输出功率达到20 kW时，端帽的最高温度约为40 ℃，温升速率约为0.8 ℃/kW。

Abstract:
In high power fiber laser system, the cladding power stripper can remove cladding light to ensure the quality of the output laser beam. The fiber end-cap reduces the optical power density of the output fiber end by expanding the output laser beam, so as to protect the fiber end face. Both of them are important core devices for stable operation of high power fiber laser system. In this paper, the integrated design of cladding power stripper and fiber end-cap is carried out. The integrated high power cladding power stripper and fiber end-cap is applied to a 20 kW beam combination system and a single fiber system. When the output power is 20 kW, the maximum temperature of the end-cap is about 40 ℃ and the temperature rise rate is about 0.8 ℃/kW.
