Paper Abstract

The single-mode fibre erbium doped optical amplifiers are well known. They have high gain in wide band. They works in telecommunication purposes mainly [1] but the idea of optical signal amplifying is interesting also in other areas. One of intriguing application is free space signal pre-amplification for example in distance meters. In such implementation the multi-mode active fibre usage should be considered. There are a few literature positions that focus on this area [2]. Therefore, the multi-mode fibre amplifiers analysis was performed by authors. This paper presents a theoretical basis of multi-mode fibre amplifiers based on energetic and propagation equations. The investigation of amplifiers pumped codirectionally and contradirectionally introduced for fibres Er and Nd doped was taken.
