摘    要:采用Ⅰ /Ⅱ角度失谐的三倍频方案 ,以超高斯光束作为入射基频光场 ,建立了位相扰动光束三次谐波转换的理论模型 ,并作数值模拟计算。结果表明 ,位相扰动不仅影响二、三倍频光的转换效率 ,还对各谐波光束质量产生影响。

关 键 词:位相扰动  六阶超高斯光束  三次谐波转换

Abstract:Using type Ⅰ/type Ⅱ angle-detuning scheme for third harmonic generation,the effect of phase ripple on the characteristic of third harmonic conversion is considered and calculated when the input fundamental field is super-Gaussian beam. The results show that phase ripple affects both doubling and tripling efficiency and beam quality of harmonic waves.
Keywords:phase ripple  super-Gaussian beam  third harmonic conversion
