Intensity profile in a distributed feedback fibre laser characterised by a green fluorescence scanning technique

By W.H. Loh, B.N. Samson and J.P. de Sandro


We report on an experimental technique for investigating the intensity profile in distributed feedback fibre lasers. By scanning along the laser length and monitoring the side green fluorescence, the intensity distribution in the laser can be inferred. With this approach, we experimentally verify the sharply peaked intensity distribution predicted for lambda/4 phase-shifted distributed feedback lasers
