We research characteristics of the photonic band gab and apply photonic fiber as gain medium to fiber lasers, finally realizing separate amplification of LP11 and LP21 high-order modes with single-mode stable pump light of LP01 mode at 980 nm. Besides, we realize LP11 mode and LP21 mode laser output of dual-wavelength. Hits: 4151 Download times: 0 View Full Text    Download reader
