Add to ORKGFrequency doubling of 1.319µm radiation by an optically-written χ(2) grating in a single-mode optical fibre is reported. A peak power of 25mW at 659nm was generated in 13cm of fibre. Phase matching is achieved by periodic modulation of the nonlinear susceptibility. Third harmonic generation of ultraviolet radiation is shown to be responsible for the creation of defect centres
