We report an all-fiber passively mode-locked laser at 1030 nm. The principle of this ultrafast laser is based on nonlinear polarization evolution occurring in a long span of birefringent fiber spliced between a polarizer and a Faraday mirror. This configuration supports a large variety of pulsed regimes: noise-like, multiple pulses, burst, and single pulse mode-lock operation. In the single pulse mode-lock regime, the pulse duration is similar to 17.8 ps at a low repetition rate of 948 kHz. The spectral bandwidth is similar to 2.2nm, the pulse energy is 68 pJ, and the polarization extinction ratio is estimated to 15 dB.
