Widely Tunable C +L Bands Multiwavelength BEFL with Double-Brillouin Frequency Shifts
A wideband multiwavelength Brillouin-erbium fiber laser (BEFL) with double Brillouin frequency spacing is demonstrated. The fiber laser structure utilizes a tunable band-pass filter and a pre-amplified Brillouin pump technique within a ring cavity. An average of six Brillouin-Stokes signals in C + L...
