“…However, the homogeneous broadened nature of EDFA gain media usually prohibits multi-wavelength operation in EDFA lasers, especially for narrow wavelength spacings, unless techniques such as careful gain equalization are used. An alternative technique for two-wavelength fiber lasers can be based on stimulated Brillouin scattering in fibers doped with either erbium [5] or thulium trivalent ions [6]. However, the spectral separation, in this case, can be limited by the width of the gain band of these rare earth dopants, which was about 100 nm.…”

Narrow linewidth light lasers are critical for many applications including quantum computing, spectroscopy, and sensing. Stimulated Brillouin scattering is a promising approach to realize highly coherent light laser emission. Here we report demonstration of a pulsed Brillouin erbium fiber laser (BEFL) operating at kHz regime. The BEFL operates at 1550.1 nm, which is upshifted by 0.09 nm from the Brillouin pump wavelength as the erbium-doped fiber was pumped above the threshold of 24.8 mW. It has a peak power of −8.4 dBm with a side-mode suppression ratio of 32 dB at 980 nm pump power of 70.5 mW. At 24.8 mW pump, the BEFL produced a pulse train operating at 12.57 kHz due to the inherent instability in relaxation oscillation, which causes the nonlinear self-pulsing mechanism in the BEFL cavity. The pulse rate increased to 77.11 kHz. As the pump power is raised to 36.2 mW. However, the more than one pulses were generated as the pump power is further increased. This is the first demonstration of a stable kHz pulse generation in BEFL cavity. The laser system is simple, compact and in all-fiber configuration.

“…Owing to several important advantages including free filter, stable output, low threshold power, narrow linewidth and equal wavelength spacing, MBFLs have been extensively investigated. For example, a broadband MBFL with an operating wavelength range of 1500-1600 nm and a frequency separation of ~9.28 GHz based on four -wave mixing (FWM) in a dual MBFL cavity was reported [10]. A simple way was proposed to generate a double-Brillouin-frequency spaced multi-wavelength.…”

A multi-wavelength bidirectional Brillouin-erbium fiber ring laser with switchable Brillouin frequency spacing (BFS) is proposed and experimentally demonstrated. In the presented Brillouin-erbium ring laser, including an optical amplifier and a highly nonlinear fiber, and without any optical isolator, due to Rayleigh scattering, stimulated Brillouin scattering, and cascaded four-wave mixing initiated successively by the Brillouin pump (BP) light, the odd- and even-order Stokes lines are generated and circulate in the opposite direction in the ring cavity. The BP light and Stokes-induced Rayleigh backscattering light also simultaneously circulate in the ring cavity. Only by adjusting BP power, the gain competition between Brillouin based Stokes and cavity modes’ oscillation can be controlled, the laser output can be conveniently switched between single BFS and odd- or even-order double BFS. In addition, under the certain BP power conditions, the proposed multi-wavelength Brillouin-erbium fiber laser also can realize switchable odd- or even-order Stokes generation and Stokes generation with single BFS, with an increasing wavelength number in turn, only by simply adjusting pump power of the erbium-doped fiber amplifier. Stability and wavelength tunability of the proposed multi-wavelength bidirectional Brillouin-erbium fiber ring laser are also investigated, respectively.
