Abstract

This paper presents the development of a CO2 laser-based heating system to simulate fast thermal phenomena on high temperature resistant FBGs dedicated to high temperature profiles monitoring within components exposed to hot plasma inside Tokamak. We have demonstrated the reliability of two optical fiber based sensing techniques to control spatial and temporal annealing measurement during high and fast thermal process.

利用瑞利散射和一阶fs-PbP光纤光栅监测单模光纤激光加热
本文介绍了一种基于CO2激光的加热系统的发展,用于模拟高温fbg上的快速热现象,该fbg专用于托卡马克内部暴露于热等离子体中的部件的高温剖面监测。我们已经证明了两种基于光纤的传感技术在高快速热过程中控制空间和时间退火测量的可靠性。
