利用受激布里渊散射过程中的光增益和吸收,提出并实验证明了一种新型的波长可调谐、频率间隔可切换的多波长布里渊光纤激光器。频率间隔可以通过仅改变布里渊泵浦功率来切换。在较低的布里渊泵浦功率下,观察到16条单布里渊频率间隔的Stokes谱线;在较高的布里渊泵浦功率下,利用布里渊泵浦的吸收,观察到7条双布里渊频率间隔的Stokes谱线。该多波长激光器可在1547 ~ 1569 nm波长范围内调谐,在光通信和传感领域具有潜在的应用价值。
We propose and experimentally demonstrate a novel wavelength tunable and frequency spacing switchable multi-wavelength Brillouin fiber laser by employing optical gain and absorption during the Stimulated Brillouin scattering process. The frequency spacing can be switched by only varying the Brillouin pump power. Up to 16 Stokes lines with single Brillouin frequency spacing are observed under the lower Brillouin pump power, and 7 Stokes lines with double Brillouin frequency spacing are realized under the high Brillouin pump power by exploiting the Brillouin pump absorption. The proposed multi-wavelength laser can also be tuned from 1547 to 1569 nm and has the potential applications in the areas of optical communications and sensing.
