Double-Brillouin-Frequency Spaced Multiwavelength Generation in a Ring Brillouin-Erbium Fiber Laser

【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 hber,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 of0.172nm(20GHz) are simultaneously obtained for 6dBm Brillouin pump power and 120mW pump power at980 nm.The influence of different Brillouin and erbium-doped-Gber pump powers on multiwavelength and tuning range are investigated in detail.更多还原
