Minute Wavelength Shift Detection of Actively Mode-Locked Fiber Laser Based on Stimulated Brillouin Scattering Effect

We analyze theoretically and verify experimentally an effective approach to detect slight wavelength shift based on stimulated Brillouin scattering (SBS) effect. The concerned wavelength variation in an actively mode-locked fiber laser (MLFL) is caused by a π -phase-shifted fiber Bragg grating ( π-...
