Gain-parameter-dependent transfer functions and phase-noise performances in a mode-locked Yb-doped fiber laser are measured in this study. It is discovered that the corner frequency in the amplitude and phase domains is determined by the absorption coefficient of the gain fiber, when the total absorption and other cavity parameters are fixed. This shows that an oscillator using gain fiber with higher dopant concentration accumulates more phase noise. Furthermore, we present net cavity dispersion-dependent transfer functions to verify the effect of dispersion management on the frequency response. We derive a guideline for optimizing mode-locked fiber laser design to achieve low phase noise and timing jitter.

利用增益诱导的 RIN 传递动力学优化锁模掺 Yb 光纤激光器的噪声特性

本研究测量了锁模掺镱光纤激光器中与增益参数相关的传递函数和相位噪声性能。研究发现，在总吸收和其他腔体参数固定的情况下，幅值域和相位域的转角频率是由增益光纤的吸收系数决定的。这表明使用具有较高掺杂浓度的增益光纤的振荡器会累积更多的相位噪声。此外，我们提出了与净腔色散相关的传递函数，以验证色散管理对频率响应的影响。我们得出了优化锁模光纤激光器设计以实现低相位噪声和定时抖动的指南。
