A novel technique is presented which uses a standard phase mask to write fibre Bragg gratings of different wavelengths. Using this method with a 266 nm Nd:YAG laser, gratings can be written from 1240 to 1550 nm using a phase mask which would traditionally only write 1286 nm gratings. This method is very stable, even with writing times of > 4 h.
