摘　　要：根据水平区熔法晶体生长的原理 ,设计制作了激光显微喇曼高温热台 ;针对不同晶体 ,采用不同的加热装置 ,构成相应的温度场 ,并对其三维方向的温度场进行了测量。在工作温度为 15 0 0K时 ,控制精度为± 0 .1K。用该高温热台和激光显微喇曼光谱仪对接 ,对TeO2 和BSO晶体在熔点温度下固液界面的激光显微喇曼光谱进行了实时测量。A heating stage was designed according to the principle of zone-melting.Different heating parts were used to construct different thermal fields according to different crystals.The thermal fields were measured in three directions.This stage has been well incorporated with the micro Raman spectroscopy.The heating stage has accuracy about 0.1K at working temperature of 1500K.The real-time micro Raman spectra of TeO 2 and BSO solid-liquid interface were measured carefully.
