The present book is aimed towards the development of NLO single crystals of p-Toluidine p-Toluenesulfonate, L-Proline Succinate, L-Arginine semicarbazide and L-lysine sulphate are exhibiting NLO property more than that of KDP, and these grown materials can be used as a better replacement for KDP to find applications in the field of opto-electronics. These crystals belong to the amino acid group, which exhibit the nonlinear optical (NLO) property remarkably. The characterization studies include single XRD analysis, UV analysis, mechanical and dielectric studies of the grown crystals. The dielectric and photoconductivity measurement were also carried out for the grown crystals to probe the nature of the conductivity. Hence, the grown crystals are to be confirmed for the single crystalline nature using XRD technique. From UV spectral analysis the required transmission range for the Second Harmonic Generation (SHG) and optical band gap have been estimated.The mechanical, dielectric, and photoconductivity studies were carried out to probe the mechanical strength and polarizability nature of the grown crystals.

: This book is based on research conducted on the growth and characterization of nonlinear optical crystals. Due to the significance of crystals in contemporary technology, crystal growth has been the focus of extensive research in both solid-state physics and materials science. This book serves as an introduction to the growth phenomena, specifics of growth processes, nonlinear optical phenomena, and characterization methods that are being used for the analysis. The book is divided into three chapters: The first chapter focuses on the experimental techniques of crystal growth. It outlines the several ways that crystals grow based on the phases they go through, such as solid-solid phase transition, liquid-solid phase transformation, and vapour-solid phase transformation. The optimization methods for growing high-quality single crystals are thoroughly presented. The benefits and drawbacks of methods of growth are reviewed. The second chapter explains the theory of nonlinear optical phenomena. The selection criteria for nonlinear optical materials are reviewed. The history of nonlinear optics and the various types of nonlinear optical materials are discussed. The role of amino acids in the formation of nonlinear optical crystals is well explained. The third chapter discusses characterization procedures that are essential in determining the quality of crystals. The several characterization mechanisms including the molecular structure, chemical composition, surface morphology, optical properties, dielectric properties, mechanical behavior, and thermal properties necessary for crystal analysis are described. We hope that this book will be valuable to researchers and students.

Present day advanced technologies heavily rely on one particular class of matter, i.e. the crystals. It is the periodic nature of the atoms and the properties arising due to the periodicity in crystals that is exploited to meet various technological feats. The technological revolutions in the semiconductor, optics and communication industries are the examples. The anisotropy in the crystals gives them enhanced properties as required in the field of non-linear optics. The field of non-linear optics became practically a reality after the invention of lasers. The coherent and monochromatic optical beams in the visible and ultraviolet ranges are in high demand due to their application in the fields like material processing, semiconductor lithography, laser micromachining, laser spectroscopy, photochemical synthesis, inertial confinement fusion and other basic scientific studies. In this thesis, work on the growth and characterization of two technologically important non-linear optical crystals has been carried out after developing the necessary instrumentation and some novel techniques for synthesis and growth. Also, studies on the glassy nature of one of the crystals have been carried out. This thesis consists of seven chapters. The first chapter gives a brief introduction to the nonlinear optical phenomenon, crystal growth and glassy state. Instrumentation is the backbone of crystal research technology. Without precision growth equipments large size crystals cannot be grown and without precision characterization instrumentation no conclusion regarding the quality and usefulness of the grown material can be drawn. The work reported in Chapter 2 describes the instrumentation developed for the growth, processing and characterization of crystals grown by solution and melt growth techniques. In low temperature solution growth, crystal growth workstations have been developed using tanks (made of acrylic), heating elements, and stirring propellers. Cooling coils have been in.

We have recently grown KLTN:(Cu, Ni, Ni/Ti) and SBT crystals and characterized their nonlinear-optical properties. The growth of these high quality crystals is a result of recent improvements in the crystal growth system; namely, improved flux uniformity and higher operating temperature. These and other materials have been characterized for application to holographic data storage and quasi-phase matched second harmonic generation. In particular, the paraelectric KLTN materials doped with Ni exhibit an enhanced long wavelength sensitivity (> 600 nm), which is desirable for recording holograms with ubiquitous He-Ne or semiconductor lasers. Furthermore, we have discovered that dynamic ferroelectric domain gratings in addition to the more common electrooptic gratings are present in SBN, a close relative of SBT. This has important applications to permanent fixing of volume holograms and tunable quasi-phase matching. To complement this experimental work, we have also derived analytical expressions for the two beam coupling process which allows us to deduce photorefractive material parameters for these crystals. This balance of experimental and theoretical work has enabled us to continually develop new materials whose properties are optimized for nonlinear optical applications.

Recent years have witnessed a great upswing in the development of new crystals. Over the past few decades, the advancement in science and technology has made single crystals indispensable for the development of new generation devices. Nearly-perfect crystals of nonlinear optics and ferroelectric materials are needed for optoelectronics, microprocessors, photonics, memories and crystals of all kinds which are required for scientific studies and new applications. Hence, there is always a continuous search for new and efficient materials. In this research we have investigated the growth and physical properties of four crystals viz. two NLO and two ferroelectric crystals. Single crystals of a new NLO material DGT and GZS are grown by slow cooling technique for the first time. GPI, TUGPI and AGPI single crystals grown in the solution growth technique have been discussed. Tri Glycine Barium Nitrate (TGBN) is studied recently in terms of its NLO and ferroelectric properties. The grown crystals were subjected to structural, optical, thermal and mechanical characterization studies. The general conclusions are given along with possible future work that could be performed on these crystals.

In the modem world, the development of science & technology in many areas has been achieved through the growth of single crystals. Large sized single crystals are essential for device fabrication and efforts are taken to grow large single crystals in short duration with less cost. Nonlinear optical (NLO) materials are expected to play a major role in photonics including optical information processing, sensor protector applications, data storage ... etc. Some organic compounds exhibit large NLO response, in many cases, orders of magnitude larger than widely known inorganic materials. They also offer the flexibility of molecular design and the promise of virtually an unlimited number of crystalline structures. The present book is aimed towards the development of NLO single crystals of L-Valinium picrate (LVP), L-Histidine hydrochloride monohydrate (LHHM), L-Serine sodium nitrate (LSSN), Bisglycine hydrobromide (BGHB) and Picolinic acid hydrochloride (PHCL) which are all excellent NLO materials are exhibiting NLO property more than that of KDP, and these grown materials can be used as a better replacement for KDP to find applications in the field of opto-electronics.
