We report a narrow bandwidth spatiotemporal mode-locked (STML) ytterbium-doped fiber laser, based on homemade carbon nanotube/polyvinyl alcohol composite film and the multimode interference filtering effect. The wavelength-tunable STML operations combined with different pulse states are achieved, including single pulse, multiple pulses, harmonics. 3-dB at single-pulse state is 103 pm, while harmonic state, it as 26 pm. To give an insight into generation of numerical simulations performed. Such laser has wide range potential applications in fields optical communication measurement, well provides favorable platform for studying evolution dynamics solitons.
