This Letter presents an all-fiber mode-locked thulium-doped fiber ring oscillator based on nonlinear polarization evolution (NPE). Pumped by an erbium-doped fiber amplified spontaneous emission source, the construction of the laser cavity consisting of only fiber optic components can operate under two different regimes of solitary and noiselike (NL) pulses. Autocorrelation measurements are performed to extract features of these two regimes.
这封信件介绍了一种基于非线性偏振演化（NPE）的全光纤锁模掺铥光纤环形振荡器。该激光器由掺铒光纤放大自发辐射源泵浦，由光纤光学元件构成的激光腔可在孤子和类噪声（NL）脉冲两种不同工作模式下运行。通过自相关测量对这两种模式的特征进行了提取。
