我们展示了一种全光纤大功率单频布里频光纤环形激光器，在1.55 μ m时最大功率为100 mW，通过使用Pound-Drever-Hall锁频方案主动稳定。与窄线宽掺铒光纤激光器的泵浦源相比，布里渊Stokes辐射的相对强度噪声和频率噪声均显著降低（约20 dB）。利用两台独立布里渊光纤激光器之间的延迟自外差技术和外差拍频技术，研究了布里渊光纤激光器的超宽谱线宽度。
We demonstrate an all-fiber high-power single-frequency Brillouin fiber ring laser with maximum power of 100 mW at 1.55 mu m, which is actively stabilized by using the Pound-Drever-Hall frequency-locking scheme. Significant reduction (similar to 20 dB) of both relative intensity noise and frequency noise was observed in the Brillouin Stokes radiation as compared with those noises of its pump source, a narrow-linewidth Er-doped fiber laser. Ultranarrow spectral linewidth of the Brillouin fiber lasers was investigated by both delayed self-heterodyne technique and heterodyne beat technique between two independent Brillouin fiber lasers.
