We present a kind of harmonic mode locking bound-state solitons in fiber laser based on molybdenum disulfide (MoS(2)) saturable absorber (SA). The locker is fabricated by depositing MoS(2) nanosheets D-shaped (DF). In the laser, two form pulses with temporal separation 3.4 ps, and are equally distributed at repetition rate 125 MHz, corresponding to 14th harmonics fundamental cavity (8.968 MHz). Single- multiple-pulses emissions also observed changing pump power optimizing DF SA. Our experiment demonstrates an interesting operation regime mode-locked shows that SA can work as promising high-power ultrafast lasers.
