【摘要】 报道了基于氧化石墨烯可饱和吸收体的类噪声脉冲拉曼光纤激光器。该激光器采用了一种由掺铒光纤谐振腔和拉曼光纤谐振腔构成的全光纤双环形腔结构。拉曼增益介质为长约700m的商用硅基高非线性光纤。当半导体激光器的抽运功率为4.16W时,得到了中心波长为1690.2nm,重复频率为250kHz,脉冲宽度为500ns的稳定的脉冲激光,其信噪比为53dB。更多还原

【Abstract】 A noise-like pulsed Raman fiber laser using graphene oxide saturable absorber is reported,which adopts the all-fiber double-ring configuration,comprised by an Er-doped fiber resonator and a Raman fiber resonator.The Raman gain fiber is a 700 m commercial silicon-based high nonlinear fiber.When the pump power of the diode laser is 4.16 W,the Raman fiber laser generates stable 500 ns pulse trains at 250 kHz repetition rate.The central wavelength is 1690.2 nm and the radio of signal to noise is 53 dB.更多还原
