Supercontinuum Generation in a Photonic Crystal Fibre

Abstract

Nearly 1000-nm broad continuum from 390 nm to 1370 nm is generated in a2-m long photonic crystal fibre. The maximum total power ofsupercontinuum is measured to be 60 mW with the pumping power of 800 mWoutput from a 200-fs Ti:sapphire laser. The evolution of the pumpinglight into supercontinuum is experimentally studied in detail. It isfound that the mechanism for supercontinuum generation has directrelations with Raman effect and soliton effect, and the four-wavemixing plays an important role in the last phase of the supercontinuumgeneration.
