Multiwavelength L-band Brillouin-erbium fiber laser with intra-cavity pre-amplified Brillouin pump

In this paper, an efficient multiwavelength L-band Brillouin-Erbium fiber laser source with preamplified Brillouin pump power in a linear cavity is demonstrated. The effects of Brillouin pump and 1480 nm pump power on the laser stability and tunability is investigated. The laser can produce up to 30-stable output channels with 10.5 GHz channels spacing.
