| Abstract: | Due to nonlinear optical processes, especially stimulated Brillouin scattering and four-wave-mixing, narrow band laser radiation cannot be transmitted unaffected through optical fibers at higher power levels. Threshold conditions for the various orders of generated sidebands and the emission spectrum are theoretically and experimentally investigated with particular emphasis on the reflectivities at the fibers ends. In addition to the increase in spectral width, also a limit of the transmission ratio of 25% at high power level was found. |
