The book provides an account of preparation of new organic nonlinear optical materials belonging to the chalcone family, characterization of grown crystals by X-ray diffraction, thermal, mechanical and spectral techniques, experimental methods for determining microscopic and macroscopic optical properties to establish a firm relationship between nonlinear optical property and molecular structure of the materials. The book addresses our understanding of the nonlinear polarization mechanism and their relation to the structural characteristics of the materials and development of materials...

Nonlinear Optics (NLO) deals with the interactions of applied electromagnetic fields in various materials to generate new electromagnetic field altered in phase, frequency, amplitude or other physical properties. The nonlinear optical properties of materials play a role in many applications. The second order nonlinear response has a wide range of applications in the field of telecommunications; optical computing, storage and information processing etc. The third-order nonlinear optical response is important in all-optical switching, signal processing, and ultrafast optical communications. The...
