A　phase-locked　bound　state　soliton　with　dual-wavelength　is　observed　experimentally　in　a　passively　mode-locked　Erdoped　fiber　(EDF)　laser　with　a　fiber　loop　mirror　(FLM).　The　pulse　duration　of　the　soliton　is　15　ps　and　the　peak-to-peak　separation　is　125　ps.　The　repetition　rate　of　the　pulse　sequence　is　3.47　MHz.　The　output　power　is　11.8　mW　at　the　pump　power　of　128　mW,　corresponding　to　the　pulse　energy　of　1.52　nJ.　The　FLM　with　a　polarization　controller　can　produce　a　comb　spectrum,　which　acts　as　a　filter.　By　adjusting　the　polarization　controller　or　varying　the　pump　power,　the　central　wavelength　of　the　comb　spectrum　can　be　tuned.　When　it　combines　with　the　reflective　spectrum　of　the　fiber　Bragg　grating,　the　total　spectrum　of　the　cavity　can　be　cleaved　into　two　parts,　then　the　bound　state　soliton　with　dual-wavelength　at　1549.7　nm　and　1550.4　nm　is　obtained.
