摘要
报道了6H-SiC衬底外延生长的石墨烯作为可饱和吸收体，环形腔结构的全正色散被动锁模掺镱光纤激光器。在注入抽运功率为250 mW时，得到稳定的重复频率为1.05 MHz的自锁模脉冲，平均输出功率为6 mW；当注入抽运功率增加到480 mW时，最大平均输出功率为20 mW，相应的最高单脉冲能量为19 nJ，激光脉冲宽度约为520 ps。
Abstract
We report all-normal-dispersion passively mode-locked Yb-doped fiber laser by graphene epitaxially grown on 6H-SiC substrates in a ring cavity configuration. Stable mode-locked pulses of the fiber laser are obtained at about 250 mW incident pump power and the pulse repetition rate is 1.05 MHz; Increasing the incident pump power to 480 mW, the average output power is 20 mW, which corresponds to single pulse energy of up to 19 nJ with pulse width of about 520 ps.
