Abstract
When doped fiber waveguides operate with high peak and average signal powers, such phenomena as gain saturation and nonlinear optical effects (the Kerr effect and self-rotation of the ellipse of polarization) become appreciable. The latter may be used for mode locking in a fiber laser. This paper gives the results of the theoretical analysis of gain saturation by signal radiation in three- and four-level fiber amplifiers. For consideration, Er3+- and Ne-doped fiber amplifiers are taken as examples. In addition, the results of the experimental study of the effect of polarization ellipse self-rotation in an Er3+-doped fiber are reported. This effect is used to perform mode locking in a fiber laser with a linear scheme. Different modes of opera- tion of such a laser are considered.
