对锁模激光器的传输线激光器模型进行了修正，使其包含了引起激光啁啾的载流子诱导折射率变化。时域动态模拟表明，这会导致脉冲变窄，光谱偏移和光谱展宽。交流驱动，直流偏置，不必要的反射，和高次谐波RF驱动的影响也进行了研究。作者目前的结果显示如何啁啾，驱动条件，端面反射率，谐波操作影响脉冲形状，稳定性和脉冲光谱。>
A transmission-line laser model (TLLM) for mode-locked lasers is modified to include carrier-induced index variations which is the cause of laser chirp. Time-domain dynamic simulations show this to cause pulse narrowing, spectral shifting, and spectral broadening. The effects of AC drive, DC bias, unwanted reflections, and higher-harmonic RF drive are also investigated. The authors present results showing how chirp, drive conditions, facet reflectivity, and harmonic operation affect pulse shape, stability, and pulse spectra. >
