基于两滤波器级联和饱和吸收体的单纵模双波长光纤激光器

A fiber ring laser was proposed and demonstrated. By cascading a bandpass filter with a bandstop filter and employing a polarization-maintaining erbium-doped fiber as a saturable absorber, a single-longitudinal-mode dual-wavelength fiber ring laser was achieved. The results show that the wavelength spacing is 0.40 nm and the side-mode suppression ratio is greater than 49 dB. The proposed laser has potential to generate microwave signal of 49.85 GHz by heterodyning the two wavelengths.
