Experimental Research on Coupling Efficiency and Stability of Fiber in Laser Jamming Test
摘要
光纤耦合效率的大小与稳定性直接影响激光干扰试验中能量的模拟精度。对 1.06滋m脉冲激光器与多模光纤直接耦合时的耦合效率进行了实验研究, 分析了激光束相对光纤接收端面不同角度入射与光纤以正弦甩动情况下的耦合效率及稳定性, 结果表明: 光纤运动情况下, 耦合效率下降很小, 偏转光纤接收端面, 由于反射损耗的影响耦合效率明显下降, 光纤耦合效率变化在 3%耀5%, 稳定性较好, 总体耦合效率满足激光干扰试验的使用要求。
Abstract
Coupling efficiency and stability of fiber influence the energy simulation precision in laser jamming test directly. Thedirect coupling efficiency of laser and multi-mode fiber is researched experimentally, the coupling efficiency and stability of fiber withlaser bean incidence at different fiber inclined surface and in sine wave swing is analyzed. The results shows that the couplingefficiency declinesa little in the swing condition of fiber and declines obviously at gradient angle due to the reflect wastage, but thetotal coupling efficiency meet the demand of laser jamming test and changes 3 to 5 percent.
