Abstract

We report on a tunable noise-like pulse (NLP) generation in a mode-locked Tm fiber laser with a SESAM. A tuning range of 1895-1942 nm, while keeping the spectral bandwidth of 10-19 nm under NLP mode-locked operation, was obtained by a tunable filter based on chromatic dispersion of telescope lenses. At the center wavelength of 1928 nm, the maximum output power of 195 mW with the spectral bandwidth of 18.9 nm was obtained. The repetition rate was 20.5 MHz and the corresponding pulse energy was 9.5 nJ. To our knowledge, this is the first report of a tunable NLP mode-locked laser based on chromatic dispersion of a lens system.

摘要

我们报道了一种采用SESAM的锁模Tm光纤激光器中可调谐类噪声脉冲（NLP）的产生。通过基于望远镜透镜色散的可调谐滤波器，在NLP锁模操作下获得了1895 - 1942 nm的调谐范围，同时保持光谱带宽为10 - 19 nm。在中心波长1928 nm处，获得了195 mW的最大输出功率，光谱带宽为18.9 nm。重复频率为20.5 MHz，相应的脉冲能量为9.5 nJ。据我们所知，这是基于透镜系统色散的可调谐NLP锁模激光器的首次报道。
