Abstract
A multi-wavelength Brillouin Praseodymium fiber laser (MWBPFL) operating at 1300â¯nm region is demonstrated based on the hybrid scheme by utilizing Brillouin gain medium and Praseodymium-doped fluoride fiber as linear gain medium. A 15â¯Â 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 8â¯dBm and the 1020â¯nm pump power of 567.2â¯mW, 36 Stokes lines with a wavelength spacing of 0.16â¯nm and 24 Stokes lines with a wavelength spacing of 0.08â¯nm are achieved. The wavelength tunability of 8â¯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.
