Multiwavelength Pulse Fiber Laser Generated by Stimulated Brillouin Scattering

Mutiwavelength lasers are of great interest as their wide applications. In this paper, a novel multiwavelength pulse Brillouin Erbium-doped fiber laser was demonstrated and its principle was given. An electro-optic modulator (EOM) was used to modulate continue wave into pulse light. The results show that, the peak values are unstable, about ±3dB, but the wavelength interval was stable, about 0.088nm. And the unstable factor was discussed. Also the influence of the Brillouin pump power on output optical spectrum was discussed in experiment. Both the wavelength number and the power of the output light increased with the increasing of pulse Brillouin pump power.
