A tunable triple dissipative solitons (DSs) mode-locked laser without a spectral filter in the all-normal dispersion (ANDi) system is reported and demonstrated. The nonlinear polarization evolution (NPE) acted as an artificial bandwidth filter for formatting the pulses with multiple DSs hysteresis phenomenon and adjusting the output wavelength with tuning. The spectral range can be adjusted from 1036.24 to 1043.44 nm, and the temporal distances between adjacent pulses are all equal to 33.9 ns. With the pump power of 560 mW, the highest output energy of the triple DSs is 48.8 nJ at a repetition rate of 2.541 MHz. Besides, the mode-locking states were stabilized during the wavelength tuning process.
