摘　　要：利用非线性偏振旋转效应实现了掺Yb3+光纤环形腔激光器的被动锁模。锁模脉冲的中心波长为1.05μm,重复频率为22.22 MHz,光谱带宽为27.066 nm。被动锁模脉冲经掺Yb3+单模光纤放大器放大,再由单光栅脉冲压缩器进行色散补偿,最终获得了脉宽为120 fs,平均功率为12.5 mW,能量达0.56 nJ的稳定激光脉冲。最后分析了输出光脉冲的稳定性。Using nonlinear polarization rotation （NPR） effect of the fiber, the passively mode-locked pulse of Yb^3＋ - doped fiber ring laser is obtained. The central wavelength of mode-locked laser is 1.05 μm, repetition rate is 22.22 MHz, bandwidth is 27.066 ran. The passively mode-locked pulse is amplificated by Yb^3＋ -doped fiber amplifier, then a single grate is used to compensate dispersion, in this way, the stable laser pulse is got, its pulse width is 120 fs, average power is 12.5 mW, energy is 0.56μm. Finally the stability of the output pulse is analyzed.
