The invention relates to a large-power multiwaveband single-core optical fiber laser which belongs to large-power broadband optical fiber lasers. All or part of rare-earth ion-doped raster with 100 percent reflection coefficient of an emitting wavelength, which is contained in a core layer is written into a core layer (6) of a single-core multi-rare-earth ion-doped area double-cladding optical fiber or all or part of rare-earth ion-doped films with 100 percent reflection coefficient of the emitting wavelength, which are contained in the core layer are plated on the end surface of the single-core multi-rare-earth ion-doped area double-cladding optical fiber; all or part of rare-earth ion-doped raster with partial reflection coefficient of the emitting wavelength, which is contained in a core layer, is written into the core layer of the single-core multi-rare-earth ion-doped area double-cladding optical fiber or all or part of rare-earth ion-doped films with partial reflection coefficient of the emitting wavele
