Nonlinear optics has become a very important subfield of optics newlinesince its inception over three decades ago In linear systems the induced newlinepolarization is proportional to the electric field and the dielectric constant the newlineoptical susceptibility are constant for each particular medium independent of newlinethe electric field However when the intensity of the light propagation newlinethrough the material is increased the above conditions cease to be constant newlineand nonlinear effect occurs The synthetic work of scientist during the same newlineperiod has resulted in abroad range of new materials whose optical and newlinenonlinear optical properties have been characterized Many of these new newlinematerials are organic newline newline%%%Reference p.207-224
