An all-fiber optical fiber amplifier with the maximum power output of 106.7 W is established based on a home-made distributed side-coupled cladding-pumped (DSCCP) Yb-doped fiber. The output characteristics of the three pumping schemes (i.e., forward, backward and bidirectional pumping schemes) are also investigated. It shows that the DSCCP fiber is applicable to the fiber laser systems with bidirectional pumping scheme. By comparing the performances of the three pumping schemes, it is found that the slope efficiency of the bidirectional pumping scheme is lower than those of the forward and backward pumping schemes.
