Abstract

In the experiment reported here, the initial pump and red-shifted solitons serve as the pump fields, and t he third harmonics in the wavelength range of 288 to 500 nm are efficiently generated based on the phase matching between the fundamen tal mode and higher order modes in a photonic crystal fiber (PCF) PCF). When the pump works at 864 nm with the average power of 300 mW, the third-harmonic signals are generated at 288 nm, 320 nm, and 500 nm, the conversion efficiency η TH increases from 0.1% to 1.3%, and the bandwidth B TH changes from 6 to 23 nm. The total efficiency of third harmonic radiation in the wavelength range of 288 nm to 500 nm, defined as the ratio of the total energy of radiation in the wavelength range of 288 nm to 500 nm to the energy of the input pump, is estimated as 2.2%..
