采用石墨烯作为腔内无源功率调制元件，我们证明了有效的激光脉冲在高脉冲能量制度与传播光和石墨烯层之间的倏逝场相互作用。石墨烯通过基于溶液的氧化石墨烯的还原来制备，并且均匀地分散到水中以用于喷射到全纤维基底（侧面抛光的纤维）上。腔内功率高达21.41 dBm，确保了稳定的高能量运行，而不会对石墨烯造成任何热损伤。所得输出脉冲的中心波长、光谱宽度和重复频率分别为1561.6 nm、1.96 nm和6.99 MHz。
Employing graphene as an intracavity passive power modulating element, we demonstrate the efficient laser pulsation in high pulse-energy regime with evanescent field interaction between the propagating light and graphene layer. Graphene is prepared by the solution based reduction of graphene oxide, and dispersed homogeneously into the water for spray onto an all-fiber substrate, side-polished fiber. With the intracavity power up to 21.41 dBm, we ensure the robust high-energy operation without any thermal damage of graphene. Resultant output pulses have center wavelength, spectral width, and repetition rate of 1561.6 nm, 1.96 nm, and 6.99 MHz, respectively.
