摘要：An optical gain device comprises an input optical fiber (21), an optical fiberadiabatic transformer section comprising a GRIN optical fiber (26) coupled to the inputoptical fiber (21), an optical fiber gain section (28), coupled to the optical fiber adiabatictransformer section, and means for optically pumping the gain section, wherein the GRINoptical fiber has a refractive index that is graded so that a light beam passing through theGRIN optical fiber (26) has a modefield that expands from the input optical fiber (21) tothe optical fiber gain section (28).
