摘要：

Fiber-optic temperature sensors based on fluorescence decay has been a subject of interest for many years now.(1) Because of their intrinsic accuracy and immunity to electromagnetic interference, they are now widely used to monitor the temperature in plasma processing systems and high voltage power transformers. We have made substantial progress in extending the high temperature capability of these sensors in recent years by adopting a monolithic crystalline fiber 2,3 approach. To date the maximum temperature we have been able to reach is 1,900 K. In this paper we present our results on Er:YAG and Yb:YAG temperature sensors, and give some guidelines for the future development of this type of thermal probes.
