摘　　要：本文用晶体区熔生长理论对激光加热基座法生长的单晶光纤形状稳定问题作了研究.说明了稳定生长的熔区长度与晶纤直径、源棒直径的关系.讨论了影响晶纤直径波动的干扰因素.指出了干扰因素中激光功率的稳定和源棒直径的均匀是主要的.理论推出的结论得到实验证实.In the paper, the shape stability of single crystal fibers grown by laser heating float zone growth method is studied with zone melt growth theory. The relation of melting zone length (1) during steady-state crystal growth to the diameters of source rod (D) and fiber (d) is explained. It is indicated that the laser heated source stability and the homogeneity of source rod are the major factors influencing the fiber diameter fluctuation. The conclusion deduced from theory agrees with the experimental results.
