摘　　要：单晶光纤作为高温传感器的关键器件在航空航天、军事研究、电力、铸造等方面有着广泛的应用。文中介绍了一种基于激光基座加热法的单晶光纤拉制系统,并通过ZEMAX光学软件对系统进行了光学仿真。软件仿真结果表明,在光学系统的聚焦点,能形成高质量的环形热源,验证了系统的优越性。为了拉出高质量的单晶光纤,对光学系统的熔区建立数学模型,并从理论分析上讨论了各种因素对单晶光纤品质的影响。由于系统有着其他激光基座加热法的光学系统无法比拟的优点,在拉制氧化锆和其他高温单晶光纤方面有着很好的应用。As the key element of the high-temperature sensor,the single crystal fiber has a wide application in the fields of the aerospace,military,electricity and casting.A single crystal fiber drawing system based on the base heating method is proposed.This system is simulated by ZEMAX optical software.The simulation result shows that the high quality ring heat source can be formed in the focus point of the optical system.In order to draw the high-quality single crystal fiber,the mathematical models of the molten zone in the optical system is established and the influences of varies factors on the single crystal fiber are analyzed theoretically.The advantages of the system are incomparable for other optical systems,so it is used widely in zirconia drawing and other high-temperature single crystal fibers.
