Abstract

A tunable multi-wavelength Brillouin–erbium random fiber laser with a half-open cavity is proposed and experimentally demonstrated. In this simple laser device, stabilized 15-order Stokes lines and 3-order anti-Stokes lines can be obtained by adjusting the pumping power. By adjusting the wavelength of Brillouin pump, the random laser wavelength tuning is realized, which can be tuned to 1550.5 nm-1565.5 nm. In addition, the laser has high wavelength and power stability. The wavelength fluctuation range of 1–10 orders Stokes light is less than 0.01 nm, and the corresponding peak power fluctuation is less than 1.8 dB. The results show that the laser has the advantages of simple structure, many spectral line orders, wide tunable wavelength range and high stability, which makes it have broad application prospects in many fields, such as fiber sensing, microwave photonics, optical imaging, optical communication systems, precision metrology and so on.
