[IEEE 2019 Workshop on Recent Advances in Photonics (WRAP) - Guwahati, India (2019.12.13-2019.12.14)] 2019 Workshop on Recent Advances in Photonics (WRAP) - Effect of M ² parameter of the fiber and the laser on the efficiency of coupling between them

摘要： We present a study on the dependence of coupling efficiency between an optical fiber and a laser on their M2 factors viz. Mf2 and M2, respectively. It is observed that the coupling efficiency is maximum for M2/ Mf2 < 1. This gives a fair idea for selection of optical fibers in coupling laser beams to optical fibers.
