Abstract
A novel structure for efficient side-coupling of high power double-cladding fiber lasers is presented. The maximum coupling efficiency of this structure is more than 90% for TM-polarization in the +1 and −1 order but is only 40% for TE-polarization. Thus, a multi-layer stair-structure is introduced and optimized by combining transmission algorithm and genetic algorithm to obtain higher coupling efficiency for η TE-polarization and the maximum coupling efficiency almost reaches to 70%.
