Stimulated Raman scattering (SRS) is one of the important factors which restrict the further improvement of fiber laser power. We propose that using chirped and tilted fiber Bragg gratings (CTFBGs) can suppress SRS. According to the design of optical fiber laser SRS signal of 1018 nm, a CTFBG of 1066 nm is fabricated. An experimental system is established to verify the filtering effect of Raman signal. Results show that the designed CTFBG can suppress the first-order SRS signal about 20 dB, and achieve a good effect. The research results have certain significance for suppressing SRS in high power fiber laser oscillator and amplifier with CTFBG, and for further improving the efficiency and output power of fiber lasers.
