Abstract: | The letter reports on the first experimental measurements of the temperature distribution along silica-based optical fibres using a semiconductor laser source and an avalanche photodiode detector. Previous results by the same authors demonstrated the first use of the Raman scattering technique, but used a less practical ion laser source and a photomultiplier detector. |
