Abstract
The operation of a single-wavelength Brillouin-erbium fiber laser (BEFL) system with a Brillouin pump preamplified technique for different output coupling ratios in a ring cavity is experimentally demonstrated.The characteristics of Brillouin Stokes power and tunability were investigated in this research.The efficiency of the BEFL operation was obtained at an optimum output coupling ratio of 95%. By fixing the Brillouin pump wavelength at 1550nm while its power was set at 1:6mW and the 1480 pump power was set to its maximum value of 135mW, the Brillioun Stokes power was found to be 28:7mW. The Stokes signal can be tuned within a range of 60nm from 1520 to 1580nm without appearances ofthe self-lasing cavity modes in the laser system. � 2009 Optical Society of America.
