The Optimization Analysis Of Organic Polymer Polarization Conditions

Based on the phenomenon that the polarized polymer nonlinear coefficient has increasingly become the focus of polymer study .The thesis puts forward and does a research on a new measure method for d 33- the standard Mark Stripe method on the original ones .In the meantime, the best polarized temperature and electric pressure of DRI/PMMA side-chain organic polymer .The initiative point of this method lies in the use of real time polarization when doing experiments ,thus avoiding the possible error if polarizing polymer before conducting measurement.It briefly introduces the optical effect and preparation of the organic polymer nonlinear optical material. In the future optical -technology- centered era, nonlinear optical material (NLO in brief) will be a critical one, while the organic polymer belongs to this kind of material .At present, the study of polymer material has caught great attention from scientists across the world .It is desirable to be widely used in such electric technology and optics fields as optical communications, counting, information-processing as well as storage etc..Ordinary polymer material doesn't have macro second-order nonlinear optical properties. One of the most effective methods for polymer material in the laser show under a great deal of macro second-order nonlinear optical properties is to contain non-symmetrical molecular structure of the centre-league polymer films in the field under the high-voltage polarization treatment ,and forced chromophore molecule along the direction of the electric field orientation. So that the original laws of the polymer is no statistical significance on macro-center symmetry. It will show the macro second-order nonlinear optical properties under the laser. In this paper we expounds organic polymer several polarization. While polarized polymer membrane enjoys the following advantages: great nonlinear coefficient and quick response nonlinearity and low dielectric constant and high laser damage threshold. Thus polarization polymer is recognized as the most development potential of one of the nonlinear material. At present, the polymer-based electro-optical effect of electro-optical modulator, light switches and other devices have started from the laboratory to the market.The thesis focuses on introducing the use of standard Mark fringe method and the Real-time polarization .The second order nonlinear intensity of the doped polymer film DR1/PMMA is measured. Comparing with the second order nonlinear intensity of the standard quarts crystal we can get the doped polymer nonlinear coefficient d 33. And at the same time, the best polarization voltage and the best polarization temperature of the doped polymer are proposed.
