We report on a wide-band and stable mode-locked all-polarization-maintaining fiber laser configuration using a nonlinear optical loop mirror. The central wavelength of the laser is 1080.14 nm and the 3 dB bandwidth is 20.29 nm. The repetition rate of the pulse is 3.28 MHz and the pulse width is 848 ps. By tuning the pump power, which is centered at 980 nm, from 300 mW to 380 mW, we obtain a linearly changed output power from 6mW to 7.12 mW. The all-polarization-maintaining fiber configuration is fundamental to the stability of the output power. [ABSTRACT FROM AUTHOR]
