NOVELTY - The utility model claims an optical fibre grating radiating device, comprising: an upper base and a lower base suitable for matching, a double-clad fibre grating set between the upper base and the lower base, and a graphene respectively set between the double-clad fibre grating and the upper base and the lower base. The utility model can meet the high power optical fibre laser under the long time and high temperature condition of double-clad optical fibre grating heat dissipation, so as to improve the stability of the double-clad optical fibre grating working.
