Abstract

Abstract

As for the temporal phase modulated broadband laser, by using some numerical techniques such as split-step Fourier transformation and fourth-order Runge-Kutta method, the effect of the intensity and bandwidth of the incident fundamental field, as well as that of the lengths of the KDP crystals on the third harmonic conversion efficiency of broadband laser have been discussed. The parameters of the mixers for the scheme of one type I doubler, one type II mixer and one type I mixer in quadrature have been optimized. The results show that using the scheme of cascade crystals can improve the third harmonic conversion efficiency and increase the dynamic range of the broadband laser tripling. For the bandwidth of 1.11 nm and the incident fundamental intensity between 3 GW/cm2 and 8 GW/cm2, the t
