为了将光纤激光器输出光纤包层中未完全被增益光纤吸收的残余泵浦光及非线性因素产生的高阶激光高效率剥离,提高剥离功率和得到较为均匀的热分布,采用优化的高折胶法制作包层功率剥离器,通过实验和有限元仿真模拟对包层功率剥离器的热效应进行了研究.实验表明包层功率剥离器剥离功率为132 W时,稳定工作温度最高为50.0℃,在此剥离条件下仿真模拟的结果与实验基本吻合,证明了仿真模型及参数的正确性,并证明了该种结构包层功率剥离器的实用可靠性.
In order to strip the fiber laser output fiber cladding is not completely absorbed by the gain fiber residual pump light and high-order laser non-linear factors generated high-efficiency peel to improve the peel power and get a more uniform heat distribution, using an optimized high-fold The thermal effect of cladding power stripper was studied by experiment and finite element simulation.The experiment shows that when the peeling power of cladding power stripper is 132 W, the stable working temperature is up to 50.0 ℃, The results of the simulation under this condition of separation are in good agreement with those of the experiment. The correctness of the simulation model and the parameters are proved. And the practical reliability of the structure-type power stripper is proved.
