Abstract

We successfully demonstrate a double-frequency spaced multiwavelength Brillouin fiber laser (MWBFL) using a dispersion shifetd fiber (DSF) as the nonlinear medium. The spectrum of the MWBFL is observed by using a standard optical specrumanalyser (OSA) with a resolution of 0.02 nm. for comparison purpose, further verifcation of the double spacing spectrum is done by observing the spectrum using a high resolution OSA with the resolution of 0.16 pm. We realized that even thespacing between two consecutive of stokes is double-frequency shifted,however there are still hidden stokes wavelength spacing of 0.08 nm.From this observation it can be deduced that even-though the above described ring configuration should by all means only allow for double-spaced Stokes outputs, in reality both even and odd Stokes lines propagate in both directions in the laser cavity.
