Abstract
We demonstrate a passive mode-locked Er:Yb doped double-clad ring fiber laser based on graphene saturable absorber. By adjusting the polarization controller and minimizing the cavity loss, the laser can operate at hundreds of harmonics of the fundamental repetition frequency of the resonator with the central wavelength of 1.61 μm. Up to 683rd harmonic (which corresponds to 5.882 GHz) of the fundamental repetition frequency was achieved.
摘要
我们展示了一种基于石墨烯可饱和吸收体的被动锁模掺铒镱双包层环形光纤激光器。通过调整偏振控制器并最小化腔损耗，该激光器可以在谐振器基频重复频率的数百个谐波下工作，中心波长为1.61μm。实现了高达基频重复频率683次谐波（对应于5.882GHz）。
