The first theoretical model of Fourier domain mode locking operation is presented. A specially tailored dynamic equation in a moving spectral reference frame is derived, enabling efficient numerical treatment, despite the broad laser spectrum and the extremely long cavity. The excellent agreement of the presented theory with experiment over a wide range of operation parameters enables a quantitative assessment of the relevant physical effects, such as the spectral loss modulation and gain saturation dynamics, amplified spontaneous emission, linewidth enhancement, and self-phase modulation.
提出了傅里叶域锁模操作的首个理论模型。推导了在移动光谱参考系中经过特殊定制的动力学方程，尽管激光光谱很宽且腔极长，但仍能实现高效的数值处理。所提出的理论与实验在广泛的操作参数范围内具有出色的一致性，这使得能够对相关物理效应进行定量评估，如光谱损耗调制和增益饱和动力学、放大的自发辐射、线宽增强和自相位调制。
