Hydrazone organics with third-order nonlinear optical effect for femtosecond pulse generation and control in the L-band

•The dissipative soliton pulses are realized in a hydrazone organic SA in a normal dispersion fiber laser, and the pulse width is further compressed to the near-transformation limit of 400 fs.•The transport characteristics of dissipative solitons outside the cavity are discussed, and dissipative soliton-like noise pulses are found in the anomalous dispersive SMF inside and outside the cavity.
