摘要
分析了 L i Nb O3 电光强度调制器的非线性调制特征 ,论述在主动谐波锁模掺铒光纤环形激光器 (AHML- EDFL)中利用该调制器的非线性来获取高阶锁模脉冲的物理机理和调制方法。在实验上 ,通过多种非线性调制手段 ,从 AHML- EDFL中获取了分频 ,2阶 ,3阶等高阶锁模脉冲序列。
Some novel methods to get the optical pulses at repetition rate (f p) integer multiples of the RF drive frequency in actively harmonic mode locked erbium doped fiber laser (AHML EDFL) are reported. The character of the nonlinear modulation is analysed. The mechanism of high repetition rate pulses generated from AHML EDFL in particular, the influence of modulation degree on pulse train are discoussed.
