Bound solitons with a soliton pulse width of 326 fs and a pulse separation of 938 fs are obtained in a passively mode locked fiber laser. Its creation and annihilation mechanism is experimentally investigated. Due to the existence of a strong cw laser in the cavity, the generation of bound solitons is found to be different from that of the nonbound normal solitons. We find that the number of stable bound soliton pairs in the cavity can be controlled only under lower pump power.
