V2：撒但这样对他最亲近的伙伴说着，把他的头抬出火焰的波浪上面，两只眼睛，发射着炯炯的光芒，身体的其他部分平伏在火的洪流上，又长又大的肢体，平浮几十丈，体积之大，正象神话中的怪物，象那跟育芙作战的巨人泰坦，地母之子，或象百手巨人布赖利奥斯，或是古代那把守塔苏斯岩洞的百头神台芬，或者象那海兽列未坦，就是上帝所创造的一切能在大海洪波里游泳的生物中最巨大的怪物：据舟子们说，他有时在汹涌的挪威海面上打瞌睡，常有小舟夜航而遇险的时候，以为他是个岛屿，抛锚扎在他的鳞皮上，碇泊在他身旁的背风处，在黑夜的笼罩中等待姗姗来迟的黎明。大魔王就是这样横陈巨体，被锁在炎炎的火湖上面，既不能起立，也不能昂起头来，但由于那统治万汇的天神的意志和他的洪量，让他自由地得逞阴谋，他心想危害别人，却终于加重自己的罪行，刑上加刑，让他懊恼地看见自己一切的恶意怎样在他所引诱的人身上带来无穷的善意、恩惠和怜悯，而在他自己身上却招来了三倍的慌乱、惩罚和报复。

This problem is also important and valuable in Nonlinear Optics. It will be very helpful to understand how the aberrations affect the course of three- wave mixing, such as the change of conversion efficiency, the distribution of intensity and phase.Small signal solution of aberrated second harmonic generation is deduced from three-dimension three wave coupling functions. The numerical work gives out lot of results of different aberrations. The effects of the fundamental waves aberrations, which will change the conversion efficiency, distribution of intensity and phase in the frequency conversion, is analyzed. 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. Results are given.
