Abstract: A high-power fiber cladding power stripper comprises a core unit, a cladding layer, a grating structure, and a jacket. The core unit is an optical conductive material. The cladding layer is disposed outside the core unit, wherein a refractive index of the cladding layer is lower than that of the core unit. The grating structure, disposed outside the cladding layer, is for producing diffraction effects. The jacket surrounds and protects the core unit, the cladding layer, and the grating structure. Hence, in a high-power fiber laser system, the cladding power stripper can be utilized for removing residual pump energy before the laser light entering an output collimator.
