Abstract:
Making use of the laser rate equations and the formalism of mode overlap in the electromagnetic theory, the authors set up the equations describing the interaction between pump and signal light in an optical fiber TW amplifier. The differential equation which governs the evolution of the density of the signal photon in the ith mode has been derived by means of the equivalent relation in optical waveguide between the normalized mode power density and the photon distribution functions. Calculations have been carried out for two typical forms of optical fiber TW amplifiers, and the variations of the gain with the ratio of pump to signal light power, the interaction length and various fiber parameters are given.
