摘　　要：Side pumping combiners are widely used in fiber laser schemes for their high coupling efficiency, low insertion loss, and multi-point pumping capability. However, side pumping combiners perform differently in coupling efficiency when pumping with a laser diode(LD) and a high-brightness 1018 nm Yb-doped fiber laser(YDFL). In this paper, for the first time, to the best of our knowledge, we investigated the different parameters to fabricate the(2 + 1) × 1 combiner with high coupling efficiency when pumping with an LD and a YDFL, respectively. After optimization, the maximum coupled pump power from one single-pump port of the combiner was 1200 W and 2730 W when pumping with a LD and a YDFL, respectively.
