Abstract: A small diameter multimode optical fiber (26) with a low numerical aperture (i.e., 0.1) is used as a microlens to collimate the output emissions of a laser diode emitters (12,14 and 16) before butt coupling the output of the laser diode array to an optical fiber bundle (24). The optical fiber used as the microlens is chosen such that its diameter roughly equals the diameter of the fibers (18,20,22) to be coupled to the laser diode emitters (12,14,16). The collimation is performed in the high NA direction of the output of the laser diode. The output of a bundle of butt coupled optical fibers may be used to pump a laser system.

Abstract translation: 在将激光二极管的输出与光纤对接之前，使用具有低数值孔径（即，0.1）的小直径多模光纤作为微透镜来校准激光二极管的输出发射。 用作微透镜的光纤被选择为使得其直径大致等于要耦合到激光二极管的光纤的直径。 在激光二极管的输出的高NA方向进行准直。 一对对接光纤的输出可以用于泵浦激光系统。
