FIBER OPTIC LASER BEAMS COMBINER FOR THREE DIFFERENT WAVELENGTHS

Resumo

In this work we describe a simple fiber optic laser beams combiner prototype for three different wavelengths. The qualitative results described here concern only two of the input branches of the combiner, i.e., only the combination of two beams will be analyzed. The preliminary results obtained are discussed and compared with those obtained from a conventional lumped beam combiner that uses seven mirrors and four beam splitters. These show the feasibility of using the present device to combine laser beams with different wavelengths. Furthermore, the results are better than those obtained with the conventional beams combiner, so far as stability and transmission coefficients are concerned.
