Abstract
Taking into account the effects of third-order nonlinear effects, transverse walk-off and diffraction etc., we have performed theoretical analysis and numerical simulation for third-harmonic generation (THG) in potassium dihydrogen phosphate (KDP). The results show that the efficiency of the THG decreases as the ratio of phase ripples of the input beam increases. The results also indicate that increasing the conversion efficiency of THG can improve the beam quality of the third-harmonic wave.
