摘要
设计了一种基于偏置相移非线性环路反射镜的全保偏锁模光纤激光器。搭建了全保偏锁模振荡器系统,该系统通过二级掺镱光纤放大获得了平均功率为2.4 W、重复频率为20.3 MHz、脉冲宽度为142fs的脉冲序列输出。由于振荡器采用全保偏光纤结构,锁模具有良好的抗环境稳定性。
An all polarization maintaining mode-locked fiber laser which is based on bias phase shift nonlinear loop mirror is proposed. An all polarization maintaining mode-locked oscillator system is set up. The system generates pulses with average power of 2.4 W, repetition rate of 20.3 MHz and pulse width of 142 fs by three stages Yb-doped fiber amplification. Since the oscillator adopts all polarization maintaining fiber structure, the mode locking is environmentally stable.
