Abstract :
Frequency doubling of 1.319 μm radiation by an optically-written χ(2) grating in a single-mode optical fibre is reported. A peak power of 25 mW at 659 nm was generated in 13 cm 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
