望远镜准直系统应用于激光的单模光纤耦合
Telescope System Used to the Single Mode Fiber Coupling of the Laser
摘要
介绍了用望远镜准直系统提高激光光纤耦合效率的方法,提出对于那些直接耦合效率非常低的系统,利用合适的望远镜准直,耦合效率可以大大提高。激光器为TA100型,1.6:1的望远镜系统使单模光纤的耦合效率达到70%,保偏光纤耦合效率达到67%。介绍了实验中两透镜距离如何影响耦合效率,望远镜系统选取的原则,及将其应用于其他激光器的情况。
Abstract
The paper introduces a way that uses telescope for increasing the coupling efficiency of the fiber. It aims at that to those low coupling efficiency system, proper telescope can increase coupling efficiency greatly. To the laser TA 100, the telescope of 1.6:1 makes the coupling efficiency of single mode fiber reach to 70%, and which of polarization maintaining single mode fiber reach to 67%. The paper also introduces how the distance of two lenses affects the coupling efficiency in experiments, how to select the telescope, and the fiber couplings of other lasers.
