摘要
报道了用氧化石墨烯作为可饱和吸收体的全光纤结构皮秒脉冲掺铒光纤激光器。该激光器的线形谐振腔由窄带的光纤布拉格光栅和氧化石墨烯可饱和吸收镜构成。当抽运功率为22mW时,实现了稳定的重复频率为5.82MHz的锁模激光脉冲输出,脉宽为87ps,光谱中心波长为1549.3nm,3dB谱宽为0.06nm,信噪比为66dB。
We demonstrate the all-fiber picosecond erbium-doped fiber lasers in which graphene oxide is used as the saturable absorber. The linear resonant cavity consists of a narrow band fiber Bragg grating and a graphene oxide saturable absorber mirror. When stable mode-locked pulses of the fiber laser occur at 22 mW incident pump power, the pulse repetition rate is 5.82 MHz and the measured pulse width is 87 ps. The spectral central wavelength is 1549.3 nm, the 3 dB spectral width is 0.06 nm and the signal-to-noise ratio is 66 dB.
