Analysis of output characteristic for fiber bragg gratings laser

A spread equation of erbium-doped optical fiber laser was derived from the basic theory of laser. Then, the hypothesis of erbium-doped optical fiber ring laser was proposed. The special computation procedure and the theoretical arithmetic emulation of output characteristic for this laser were conducted by discussing the effect of the configuration. Moreover, this article further investigated the influence of the relationship between pumping and laser output, cavity distribution of gas gain, slope efficiency and the influence that the output coupling rate parameters having on the laser output of optical fiber laser.
