摘要
报道了一种新型的采用大色散腔结构的光纤锁模激光器 ,它可以有效地克服激光器腔长抖动对锁模的不良影响。同时 ,实验中发现 ,该结构对超模噪声也有很好的抑制作用。完成了大色散腔、电光调制器调制的 ,稳定的光纤锁模激光器实验 ,得到形状为sech2 的光脉冲输出 ,脉冲宽度为 7 6 ps,脉冲带宽积为 0 335。
A stable mode locked fiber ring laser with large dispersion cavity is demonstrated. In this laser, the instability caused by cavity length excursion is suppressed. At the same time, the super mode noise is suppressed too. A 10 GHz mode locked erbium doped fiber ring laser using a large dispersion cavity developed, in which the pulse repetition rate is 10 GHz with sech 2 profile, the pulse width (FWHM) measured by autocorrelation meter is 7.6 ps, and the time bandwidth product is approximately 0.335.
