Abstract

Highlights: Multi-wavelength Brillouin Praseodymium fiber laser (MWBPFL). Operates at 1300 nm region using Stimulated Brillouin Scattering (SBS). 15 µm air gap allows switching of frequency spacing from double to single. 36 and 24 Stokes lines with 0.16 nm and 0.08 nm wavelength spacing achieved. Tunability realized by shifting Brillouin pump wavelength. Abstract: A multi-wavelength Brillouin Praseodymium fiber laser (MWBPFL) operating at 1300 nm region is demonstrated based on the hybrid scheme by utilizing Brillouin gain medium and Praseodymium-doped fluoride fiber as linear gain medium. A 15 µm air gap is incorporated into the cavity to allow the switching of Brillouin frequency spacing from double to single spacing. Under the Brillouin pump of 8 dBm and the 1020 nm pump power of 567.2 mW, 36 Stokes lines with a wavelength spacing of 0.16 nm and 24 Stokes lines with a wavelength spacing of 0.08 nm are achieved. The wavelength tunability of 8 nm is realized for both MWBPFLs by shifting the Brillouin pump wavelength. The MWBPFLs exhibit an excellent stability in the number of generated Stokes and power level over one-hour period.
