A compact all-fiber polarization-maintaining Er:laser using a nonlinear amplifying loop mirror is reported.Fundamental single-pulse mode-locking operation can always self start,with a cavity round-trip decreased from ～ 4.7 m to ～ 1.7 m.When the pulse repetition rate is 121.0328 MHz,output pulse is measured to have a center wavelength/3-dB spectral bandwidth/radio frequency signal to noise ratio (SNR)/pulse width of 1571.65 nm/18.70 nm/80 dB/477 fs,respectively.Besides,three states including the exponential growth,damping state,and steady state are investigated through the build-up process both experimentally and numerically.Excellent stability of this compact Er:laser is further evaluated,demonstrating that it can be an easy-fabrication maintenance-free ultrafast candidate for the scientific area of this kind.
