We experimentally demonstrate an all-fiber mode-locked Erbium-doped fiber laser (EDFL) using single walled carbon nanotubes (SWCNTs), which is embedded into polyvinyl alcohol (PVA) as a saturable absorber. The laser generates a self-starting dissipative soliton pulse, which operates in 1533.6nm region without any additional spectral filter as a 980nm pump power is increased above the threshold value of 35.2mW, respectively. The output solitons have a pulse duration of 1.8ps with a repetition rate of 15.3MHz. At pump power of 71.0mW, the pulse energy and peak power are approximately 0.28nJ and 148W.
