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.

Was the same corpse exhumed and mutilated after Charles II came to the throne, ending Britain's brief experiment with republicanism and military rule? Was it really the Lord Protector's head that was rammed on a pike in Whitehall, to discourage regicides, only to be blown down in a gale and swiped by a soldier? And was it really that same head, battered and worm-eaten, with an iron spike still rammed through the skull, that became a souvenir, a vulgar curiosity, a treasured relic and was finally in 1960 secretly laid to rest in the chapel of Sidney Sussex College, Cambridge, where the young Cromwell briefly studied?
