Abstract

The third harmonic frequency conversion efficiency curves of Gaussian beams similar to Flattened Gaussian beams(FGB’s) having increasing integer N were obtained. The efficiency curves versus the crystal lengths, the pumping wave polarization ratio, the order of the FGB’s and the pump power intensity have been calculated by computer simulation. The conversion efficiency of third harmonic generation of the Flattened Gaussian and Gaussian beams were obtained in detail numerical stimulation for CsLiB6O10. The conversion efficiencies of 96% of the flattened Gaussian are larger than that of Gaussian efficiencies of 88% in type-II (1) phase matching.
