摘要
The fabrication of fiber Bragg gratings by the fourth harmonic of a Nd:YAG laser was described. This is the first report of writing with this kind of ultraviolet light source. The spatial and temporal coherence of laser beam is improved by applying a F-P etalon and a diaphragm of small aperture. The fiber was placed in an interferometer and exposed for 60 minutes. As a result, about 3% reflection was observed at 1505 nm.
