The experimental system of SBC has be extended from two elements to three elements. Influences of focal length of lens on coupling efficiency and beam quality were analyzed. The tunable output of a fiber laser with different focal lengths of lens was compared experimentally. The experimental data of SBC with different focal lengths of lens were investigated.
