Investigation on the Growth and Properties of Non Linear Optical Crystals

Crystal growth and characterization is a vital and fundamental part in the field of surface physics crystallography material science and engineering. Crystals of good quality and perfection are required for practical devices such as detectors transducers solid state lasers frequency converters and for other millions and millions of applications. Thus many new crystals must be grown in order to evaluate their device properties. The development of scientific instruments and analytical methods makes it possible to understand the optical thermal mechanical and other properties of crystals. The technological development depends critically on the availability of suitable single crystals. The application of semiconductor based electronics creates a demand for high quality ferroelectric piezoelectric and optical single crystals. After the introduction of nonlinear optics the nonlinear effects are used as scientific tools to investigate physical and chemical processes in atoms molecules crystals thin films and polymers that are promising for commercial device applications. The importance of NLO phenomena leads to the development of nonlinear optical materials.
