【摘要】 本文比较系统地分析了光纤中泵浦光向拉曼斯托克斯光转换的过程,同时讨论了斯托克斯光随注入泵浦光变化的情形,引入了泵浦阈值功率的概念,为分布式光纤温度传感器系统打下了理论基础。更多还原

【Abstract】 The transfering process of the laser pump power in optical fibers ro Raman Stokespower is analysed systematically, and the variance of Stokes power with the injection ofpump power is discussed at the same time,and the concept of pump threshold power is intro-duced,thus lay a basis for the distributing optical fiber temperature sensor system in theory.更多还原
