Abstract

Employing a highly nonlinear, 4.5-meter-long Erbium-doped fiber (EDF) as the hybrid gain medium, a self-Q-switched laser produced the Q-Switched pulses in multiwavelength. The laser's repetition rate could be adjusted between 15.46 and 57.31 kHz, and its center operating wavelength was approximately 1594 nm. A multi-wavelength Brillouin Erbium fibre laser (BEFL) operating in the L-band was successfully activated using stimulated Brillouin scattering (SBS). By varying the input pump power within the range of 64.8 mW to 259.4 mW, the pulse width can be controlled from 16.14 to 8.50 μs using less than 156.4 mW of pump power. The SBS-based Q-switched laser showed exceptional stability with a maximal pulse energy of 84.10 nJ, and the fundamental radio frequency signal-to-noise ratio (SNR) reached a high of 70.45 dB. Notably, no actual saturable absorber components were used in this experiment, making it the first successful implementation of a BEFL with multi-wavelength output that is Q-switched using SBS.
