It shows that when walk - off and diffraction effects could be ignored approximately estimation of the phase distribution of second - harmonic wave could be done. the far field divergent angle and second moment radius of harmonic wave will vary with the aberration of fundamental wave, but the far field divergent angle will be obviously smaller than that of fundamental wave. the phase distribution of both fundamental and harmonic wave is measured using hartmann - shack wave front sensor in the experiment with 1064nm and 790nm lasers, respectively這說明利用非線性光學頻率變換 方 法拓寬波前傳感器件的響應波段是很難實現的,但是,通常三波相互作用過程的研究均是建 立 在 平 面 波和理想高斯光束之上,因此我們對于位相畸變倍頻過程的研究是非線性光學領域一個重要而有意義的新課題,它有助於人們更加深入理解非線性光學效應,為進一步合理利用之奠定了理論和實驗的基礎。
