摘要
本文介绍了将半导体激光器耦合到光纤维的平凸自聚焦透镜的性质,并且给出了一些计算透镜参数的公式。通过分析指出,当需要使用大数值孔径的自聚焦透镜或自聚焦透镜不能充分靠近光源时,采用平凸自聚焦透镜是有益的。
This paper describes the properties of the piano- convex selfoc lenses for coupling laser to fiber and gives some formlae to calculate the parameters of the selfoc tenses. It is also shown that when higher numerical aperture or longer distance from the lens to the laser is needed the piano- convex selfoc lens may be adapted.
