摘　　要：在采用大面积半导体激光器阵列进行泵浦时,由于能量密度等因素,必须把泵浦光会聚到很小的面积上。而空心导光管作为一种良好的耦合器件,不仅能够实现匀光缩束的功能,还具有高效、简洁、可控制光斑形状等优点。在阐述了采用Duct进行半导体激光器阵列缩束整形的原理后,通过对Duct近似模型的分析,得到了Duct的优化结构参数,并通过光线追迹得到了Duct输出光斑的特性。When employing the large area semiconductor laser diode array for pumping, it is compulsory to focus pumping energy on a small point because the reason of energy density. As a good coupling instrument, hollowing duct can not only realize the function of compress and uniform the beam, but also have the advantage of high efficiency, simple and can easily control the shape of the beam. After introducing the theory of using semiconductor laser diode array of shaping, through simulations of the duct similar model, optimized structure parameters and the characteristics of its output spot are obtained by ray tracing.
