Abstract :
Red-shifted solitons serve as the pump fields, and the second and third harmonics at 550, 570 and 700 nm are simultaneously generated for the first time in a photonic crystal fibre. The conversion efficiency h increases from 0.15 to 1.5%, and the bandwidth B changes from 6 to 16 nm. The maximum efficiency of the pump to the second and third harmonics is estimated as 2.35%.
