An effective non‐linear optical limiting technology is proposed here based on backward stimulated Brillouin scattering in grade‐index optical fibres. The excellent non‐linear optical limiting performance is experimentally verified by using 0.5 and 1 m grade‐index quartz fibres at the wavelength of 1064 nm. The linear transmittance for 0.5 and 1 m fibres are both beyond 96% and the lowest non‐linear transmittance are 6.1% and 1.5%, respectively. This is the best non‐linear optical limiting performance that can be achieved at present.
