Abstract
In this paper, we propose and demonstrate a novel method for the suppression of SBS in optical fibers using a tilted fiber Bragg grating (TFBG). We designed and fabricated a matched TFBG by using an excimer laser and phase mask in single mode fibers according to the operating wavelength of the fiber laser and the tiny frequency shift of SBS. Experimental results demonstrate that TFBGs can suppress the backward-propagating Stokes light caused by SBS to protect the whole system and improve the stable output power, which is very useful for power scaling of high-power narrow-bandwidth all-fiber laser in the future.
