我们提出利用一小段保偏光纤作为双折射介质，在光纤激光器腔内构建全光纤Lyot滤波器。这允许全光纤全正常色散yb光纤振荡器的锁模操作，而不使用散装带通滤波器和使用标准组件。此外，通过改变保偏光纤段的长度和拼接角度，可以很容易地控制滤波器的带宽和调制深度，从而实现可调滤波器。在锁模操作中，30%输出光纤端口提供1 nJ脉冲，解码为230 fs持续时间。(C) 2010年美国光学学会
We propose the use of a short section of polarization-maintaining fiber as a birefringent medium to construct an all-fiber Lyot filter inside the cavity of a fiber laser. This allows mode-locked operation of an all-fiber all-normal dispersion Yb-fiber oscillator without the use of a bulk bandpass filter and using standard components. Moreover, filter bandwidth and modulation depth is easily controlled by changing the length and splice angle of the polarization-maintaining-fiber section, leading to an adjustable filter. At mode-locked operation, the 30% output fiber port delivers 1 nJ pulses that are dechirped to 230 fs duration. (C) 2010 Optical Society of America
