Abstract: (2073 Views)
High power fiber lasers and amplifiers have many applications in the military industries; high energy physics experiments; surface processing and smoothing; cutting, and welding. In the high power fiber amplifiers; due to the existence of quantum defects, background loss and scattering of light, the ambient temperature increases; which cause to change the refractive index of the environment. The variation of the refractive index causes to mode coupling in the high power fiber lasers and amplifiers. In the present paper; the modes coupled equations are solved using Ronge-Kutta method and transferred power value between modes are determined.
