Abstract :
Coherent ultraviolet generation from the intense infrared radiation in a GeO2-doped glass fibre is theoretically investigated. It is shown that the conversion efficiency markedly depends on the transverse profile of nonlinear susceptibility in the vicinity of the core centre. This provides a candidate for the model that explains experimental results already published.
