Abstract

A sapphire fiber thermometer probe with Cr3+ ion doped tip end was grown from the laser heated pedestal growth method. The fiber probe offers advantages of compact construct, high performance and ability to withstand high temperature. The temperature dependence of fluorescence of the probe was investigated, and a sapphire fiber thermometer based on its fluorescent decay was presented. Among the detection rang from the room temperature to 450 c , the thermometer has an average temperature resolution of 10C.The thermometer may be used in microwave treatment and thermal monitoring of Medium Voltage substations.
