摘　　要：用激光加热基座法生长出了端部掺 Cr3+的蓝宝石光纤荧光温度传感头 ,其具有结构紧凑、耐高温等特点 ;研究了掺 Cr3+的蓝宝石光纤荧光温度特性 ,并制得蓝宝石光纤荧光温度计 ,其测温范围为室温到 4 5 0℃ ,分辨率 1℃。A sapphire fibr thrmal probe with Cr3+ ion doped end was grown from the laser heated pedestal growth method. The fluorescence thermal probe offers advantages of compact construct, high performance and ability to withstand high temperature. The temperature dependence of fluorescence of the probe was studied, and a sapphire fiber thermometer using its fluorescent decay was presented. Among the detection rang from the room temperature to 450°C, the thermometer has an average temperature resolution of 1 °C.
