The invention relates to an optical fiber, an optical amplifer, an optical fiber laser, and a manufacture method for optical fiber primary prefabticated member. The invention relates to a radiation-insensitive optical fiber doped with rare earths, comprising, from the center toward the periphery: a central core (11) adapted to transmit and to amplify an optical signal, the central core (11) consisting of a core matrix comprising nanoparticles, the nanoparticles being formed of a nanoparticle matrix comprising dopants from the rare earths group; an optical cladding surrounding the central core (11) adapted to confine the optical signal transmitted by the central core (11), the optical cladding having a plurality of holes (10) that extend along the length of the optical fiber, the holes (10) being separated from each other by a pitch (Lambda hole ); and an outer cladding.
