    Picosecond pulse Yb-doped fiber laser source based on a MOPA configuration. ISO, optical isolator.
    (a) Typical output power and slope efficiency of an oscillator, and (b) amplified output power and slope efficiency.
    (a) Output spectra versus different output power. All the curves are measured by an optical spectrum analyzer with 0.02 nm resolution. (b) Intensity autocorrelation trace of an amplified mode-locked pulse.
    (a) Spectra versus laser power from 8 to 71 mW. (b) Spectra versus laser power from 82 to 172 mW. The bandwidth of the FBG in the fiber oscillator is 0.22 nm.
    Spectral evolution of the incident spectra introduced by SPM with a nonlinear Schrödinger equation fast Fourier transform algorithm: (a) Spectral bandwidth of 0.18 nm, (b) Spectral bandwidth of 0.12 nm.
    (a) Spectra versus laser power from 8 to 71 mW. (b) Spectra versus laser power from 82 to 172 mW. The bandwidth of the FBG in the fiber oscillator is 0.15 nm.
