Abstract

We examine the features of second-harmonic generation (eo–e and oe–o phase matching) and third-harmonic generation (oo–e phase matching) by laser pulses with opposite frequency chirps in the saturation regime, based on numerical simulations. The influence of the material dispersion of the crystal, spectral phase mismatch, and spatial drift on the conversion efficiency and the preservation of the pulse shape at the sum frequency is investigated.

具有相反频率啁啾的宽带激光脉冲在饱和状态下产生和频特性

在数值模拟的基础上，我们研究了饱和状态下具有相反频率啁啾的激光脉冲产生的二次谐波（eo-e和oe-o相位匹配）和三次谐波（oo-e相位匹配）的特征。研究了晶体的材料色散、光谱相位失配和空间漂移对转换效率和脉冲形状保持的影响。
