The invention provides a clad light stripper capable of monitoring the output power of a high-power optical fibre laser in real time. The clad light stripper comprises a double-clad optical fibre, a dehydroxyl glass tube, a metal shell, a light attenuation piece and an optical power detector; the metal shell is hollow; furthermore, a light attenuation piece through hole is arranged on the outer wall; the dehydroxyl glass tube is fixed in the metal shell; the double-clad optical fibre is arranged in the dehydroxyl glass tube; the light attenuation piece is arranged in the light attenuation piece through hole; the optical power detector is arranged on the light attenuation piece, and is outside; and, after a coating layer and an outer cladding layer are stripped from the double-clad optical fibre corresponding to the light attenuation piece through hole, the remaining inner cladding layer is roughened by adoption of a chemical reagent. By means of a device for calibrating signal light output by the laser by mon
