信号带宽对光纤放大器模式不稳定性阈值的影响

Influence of signal bandwidth on mode instability threshold of fiber amplifiers

Jesse J. Smith, Arlee V. Smith

摘要:

我们展示了信号线宽如何影响受激热瑞利散射(STRS)的增益,这是光纤放大器中模式不稳定性的原因。如果信号的相干时间小于模式LP $_{01}$和LP $_{11}$之间的群速度引起的走离,则增益减小。我们推导出短脉冲,线性啁啾,和一般周期性的情况下的方程。

英文摘要:

We show how signal linewidth affects the gain of stimulated thermal Rayleigh scattering (STRS) which is responsible for mode instability in fiber amplifiers. The gain is reduced if the coherence time of the signal is less than the group velocity induced walk off between modes LP$_{01}$ and LP$_{11}$. We derive equations for short pulses, linear chirps, and general periodic cases.
