摘　　要：We theoretically propose the structure of all-solid photonic band gap fiber to support LP_(01) mode at 980 nm and four modes of LP_(01),LP_(11),LP_(02) and LP_(21) at C bands.We research characteristics of the photonic band gab and apply photonic fiber as gain medium to fiber lasers,finally realizing separate amplification of LP_(11) and LP_(21) high-order modes with single-mode stable pump light of LP_(01) mode at 980 nm.Besides,we realize LP_(11) mode and LP_(21) mode laser output of dual-wavelength.We theoretically propose the structure of all-solid photonic band gap fiber to support LP_(01) mode at 980 nm and four modes of LP_(01),LP_(11),LP_(02) and LP_(21) at C bands.We research characteristics of the photonic band gab and apply photonic fiber as gain medium to fiber lasers,finally realizing separate amplification of LP_(11) and LP_(21) high-order modes with single-mode stable pump light of LP_(01) mode at 980 nm.Besides,we realize LP_(11) mode and LP_(21) mode laser output of dual-wavelength.
