| Abstract: | Firstly, this thesis describes the definition of nonlinear optics, and has a brief demonstration of its developed history. Through introduction of the effect of nonlinear electric polarization, the process of the two order nonlinear optics and the formed mechanism of the second harmonic in the nonlinear optics is mainly discussed. Moreover, the specification of the test installation is described in detail. After that, we can get the coupling equations of the second harmonic from Maxwell equations, and have an analysis of the coupling equations. The result of it greatly helps the improvement of the design of optic - double - frequency instrument. Lastly, some features of optic - double - frequency instrument and the materials are introduced, and the micrography of the second harmonic is discussed in applications of medicine. |
