摘要：An optical apparatus includes one or more pump sources situated to providelaser pump light, and a gain fiber optically coupled to the one or more pump sources, thegain fiber including an actively doped core situated to produce an output beam, an innercladding and outer cladding surrounding the doped core and situated to propagatepump light, and a polymer cladding surrounding the outer cladding and situated to guidea selected portion of the pump light coupled into the inner and outer claddings of thegain fiber. Methods of pumping a fiber sources include generating pump light from oneor more pump sources, coupling the pump light into a glass inner cladding and a glassouter cladding of a gain fiber of the fiber source such that a portion of the pump light isguided by a polymer cladding surrounding the glass outer cladding, and generating a
single-mode output beam from the gain fiber.
