The Azo Dye-doped Polymer Thin Films Of Nonlinear Optical Properties Of Measurement And Research

Nonlinear optics optical disciplines as a brand-new branches. In the new high-brightness light source-After the advent of laser, In the face of her new show in the world . A short span of 40 years in the basic principles of nonlinear optics, new materials research, the discovery of new effects and applications have been tremendous development. Optical disciplines become the most active and most important branches .Azo compounds are a class of photoisomerization characteristics of the organic optical materials . Its molecular structure to nitrogen double bond connecting the nitrogen substituent is characterized by different. Azobenzene dyes in order to function as a new type of polymer optoelectronic materials in liquid crystal display, optical recording, and integrated optical device applications, such as the prospect of good .This paper reviews the theory of nonlinear optical knowledge, on azo nonlinear optical properties of materials. Focuses on the third-order nonlinear optical properties of the theory part, and then from the causes and to discuss the results of such a nature of non-linear optical phenomena. Described in detail the nature and application of azo dyes ,Including the nature of the azo dye dichroism, optical storage and nonlinear optical properties and absorption. Experiment to measure the adoption of specific azo dye-doped polymer nonlinear optical properties, experimental study of the phase conjugation light intensity and the detection of light intensity, the pump light intensity, detecting light and the angle between the pump and pump the relationship between the optical polarization direction, Records changes in light intensity conjugate curve analysis conjugate record changes in light intensity curve. Research on the use of four-wave mixing characteristics of optical storage technology.
