摘要
We demonstrate the double-Brillouin-frequency spaced multiwavelength generation at room temperature by using a simple ring Brillouin-erbium fiber laser.The Brillouin pump is pre-amplified before entering the single-mode fiber,the odd Stokes and even Stokes are amplified in two opposite directions.All amplification provided by a home-made bi-directional operation erbium-doped fiber may achieve high intensity of Brillouin Stokes that leads to the homogenous gain saturation.Twelve even Stokes and thirteen odd Stokes with a wavelength spacing of 0.172 nm(20 GHz)are simultaneously obtained for 6 dBm Brillouin pump power and 120 mW pump power at 980 nm.The influence of different Brillouin and erbium-doped-fiber pump powers on multiwavelength and tuning range are investigated in detail.
