报道了一种采用石墨烯可饱和吸收体的被动锁模铥钬共掺光纤激光器。在重复频率为0.964MHz时，获得了稳定的纳秒脉冲，脉冲能量达35 nJ。通过简单地改变泵浦光功率，获得了1897.69 ~ 1930.27nm的可调谐输出光谱。更高的输出脉冲能量是有希望的，但受到光纤部件的损伤阈值的限制。
We report a passively mode-locked thulium, holmium-codoped fiber laser with graphene saturable absorber. Stable nanosecond pulse with output pulse energy up to 35 nJ is obtained at the repetition rate of 0.964 MHz. The tunable output spectral range is from 1897.69 to 1930.27 nm by simply changing the pump power. Higher output pulse energy is promising but limited by the damage threshold of the fiber component.
