Abstract

Many conventional long-haul transmission lines are operated at λ = 1.32μm. The problem of all-optical amplification is not solved yet for this wavelength range. In line Raman amplification seems to be promising. Unfortunately there is also no efficient light source for the Raman pump wave at λ = 1.24μm. It was proposed to generate this light by a Nd:YAG-laser operating at λ = 1.06μm and to convert it down via a three stage Raman process. Recently some progress could be achieved by the introduction of Ge-doped fibres with low excess losses but with enhanced Raman gain. The aim of this paper is to model and to optimize a fibre resonator for this scheme.
