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.

This critical variable is named as creative self-efficacy after a comprehensive review of two trends of research, one about the effects of social environment on creativity and the other, effects of intrinsic and extrinsic motivation (Amabile, 1996). Then, five variables were considered important in constructing a social cognitive model of creativity, that is, significant others' feedback (about one's creativity works), inner process (including intrinsic motivation, extrinsic motivation, and creative self-efficacy), and creative behavior. Descriptive statistics, hypothesis tests of differences, and cluster analysis were adopted in analyzing data.
