Influence of L Threonine on the growth structural mechanical and nonlinear optical properties of L Tartaric acid LTartaric acid nicotinamide and thiourea single crystals

Abstract

The crystals are an essential and fundamental component of the science and engineering of materials In recent decades interest in crystal growth processes has increased with increasing demand for materials for technological applications For all solid state applications the study of crystalline materials has contributed greatly to the understanding of materials and has led to many advances in science and technology such as laser diode technology Nonlinear Optical NLO single crystals are capable of extending the available spectral region of laser radiation by the process of frequency conversion The most important limitation to exploiting the potential of the photonic process is the difficulty of obtaining suitable material It turns out that most available materials do not simultaneously meet the requirements for large and fast nonlinearity requirement for practical devices It has been found that many organic and inorganic crystals are excellent optical materials As crystal is a basic building block of a solid state material growing newer and better crystals from existing is inevitably important The desire to utilize the properties of these materials in applications such as telecommunications optical data storage and optical information processing has created need for new materials with large second order susceptibilities To enable a material to be potentially employable in NLO applications the material should be in the bulk single crystal form The employability of single crystals in practical device applications has been impeded by their often inadequate transparency poor optical quality and low laser damage threshold Hence new frequency conversion materials primarily concentrated on organic NLO materials with high nonlinear susceptibilities are to be explored newline
