Realization of an all-fibre self-organization intra-cavity coherent erbium-doped fibre laser

摘要

An intra-cavity coherent coupling Michelson Er-doped fibre (EDF) laser (MCEDFL) is proposed and demonstrated. Characteristics of the MCEDFL are investigated. It is found that the MCEDFL with a polarizer can be coherent combined effectively, By the experiment based on fibre Bragg gratings (FBGs) with different reflectivity, we End that the reflectivity of the FBG play a vital role in improving the performance of the MCEDFL. This outcome adequately shows many favourable features, such as high efficiency, easy operation, and simple all-fibre configuration.
