Paper Abstract

A novel structure for efficient side-coupling of high power double-cladding fiber laser is presented. The maximum coupling efficiency of this structure is more than 90% for TM-polarization in +1 and -1 order but is only 40% for TE-polarization. Thus, a two-layer structure is introduced to obtain higher coupling efficiency for TE-polarization and maximum coupling efficiency almost 70% is demonstrated.
