摘要
单晶光纤(SCF)是具有纤维结构的“准一维”功能晶体材料,在高能激光、高温传感、辐射探测、信息通信等国防民生领域展现出了巨大的应用前景。本文采用激光加热基座技术成功制备出直径60~100μm、长径比>6000∶1的超细Al_(2)O_(3)、YAG单晶光纤,单晶光纤平均直径起伏<4%,展现出良好的柔韧性与波导特性,为单晶光纤器件的小型化与集成化创造了条件。
Single-crystal fiber(SCF)is a kind of fibrous functional crystalline material with“quasi one-dimensional”structure,exhibiting great application prospects in the fields of high-energy lasers,high-temperature sensing,radiation detection,information communication and other areas of national defense and national livelihood.In this work,ultrafine Al_(2)O_(3) and YAG single-crystal fibers with the diameter from 60μm to 100μm and length-to-diameter ratio greater than 6000∶1 were grown by laser heated pedestal growth(LHPG)technique.The diameter fluctuation of the obtained SCF is less than 4%,demonstrating excellent flexibility and waveguide characteristics.This work presents feasible approach for the miniaturization of SCF devices method.
