摘要

We demonstrate a femtosecond mode-locked erbium-doped fiber laser (EDFL) using a nickel oxide (NiO) as a saturable absorber (SA).NiO nanoparticles are hosted into polyethylene oxide film and attached to fiber ferrule in the laser cavity.The NiO-SA shows a 39％ modulation depth with a 0.04 MW/cm2 saturation intensity.Our ring laser cavity based on erbium-doped active fiber with managed intracavity dispersion has the ability to generate ultrashort pulses with a full width at half-maximum (FWHM) of around 2.85 nm centered at 1561.8 nm.The pulses repeat at a frequency of 0.96 MHz and duration of 950 fs.
