We report the experimental observation of soliton molecules in a dispersion-managed thulium-doped (Tm-doped) fiber laser utilizing black phosphorus saturable absorber (BP-SA). A variety can be detected with increase pump power and adjustment cavity polarization state. Additionally, we use numerical simulation to investigate dynamics further explore variable controllable properties. Stable separation-changeable molecule has been numerically observed through changing small signal gain G cavity. These results enhance research into multi-soliton complexes as well its practical application.
