摘要

摘要: 为探索光纤布拉格光栅在高能参数测量方面的应用,通过实验和数值模拟研究分析了其在高能辐照下的响应特性。通过解传热方程,获得了光纤布拉格光栅在高能辐照下的热响应特性。利用一个光纤光栅解调仪,记录了光纤布拉格光栅在高能辐照下的波长漂移现象。实验结果表明:在一定的功率密度范围内,光纤布拉格光栅的最大波长漂移与其所受的辐照功率密度成线性关系,该结果与理论模拟相符。

Abstract: The response characteristics of a Fiber Bragg Grating(FBG) irradiated by high energy laser beams are investigated both theoretically and experimentally to explore the possible applications of the FBG to High Energy Laser(HEL) parameter measurements. The thermal response characteristics of the FBG irradiated by HEL beams are obtained by solving the heat transfer equation using certain approximations. The resonance wavelength information of the FBG is recorded with an interrogator. The experimental results show that the maximum resonance wavelength shift of the FBG changes linearly with the irradiating power density within a certain range, which agrees with the results of numerical simulation.
