Nucleation, growth and characterization of L-tartaric acid—nicotinamide NLO crystals

Growth and characterization of l-Tartaric acid, an NLO material

“…Also, L-Tartaric acid has higher solubility in water, could be crystallized into bigger sizes and costs much less in comparison with the amino acid-NLO materials. A number of tartaric acid complexes are known to possess NLO property [7][8][9]. However, to our knowledge, no systematic non-linear optical studies appear to have been carried out for the crystals of L-Tartaric acid (Fig.…”

Growth, structural investigation and characterization on novel organic NLO single crystal: Tri-nitrophenol para hydroxyacetophenone

“…The nonlinear refractive index coefficient n 2 , the nonlinear absorption coefficient b and susceptibility w (3) for solution of tri-nitrophenol p-hydroxyacetophenone in methanol using the Z-scan technique with 532 nm diode-pumped Nd:YAG laser are given in Table 2. The Z-scan measurements indicate that the trinitrophenol p-hydroxyacetophenone exhibits negative nonlinear optical properties.…”

“…The Z-scan technique [13] is a simple but very accurate method to determine both nonlinear index of refraction n 2 and nonlinear absorption coefficient b. Nonlinear index of refraction is proportional to the real part of the third-order susceptibility [Re w (3) ] and the nonlinear absorption coefficient is proportional to [Im w (3) ].…”

“…The field of nonlinear optics has been in the hands of materials scientists for the past five decades for which organic materials are attracting a great deal of attention, as they have large optical susceptibilities, inherent ultrafast response time and good optical properties as compared to that of inorganic crystals [1,2]. In the last three decades, many researchers have been in search of small organic molecules having large dipole moment and a chiral structure [3][4][5]. The growth of organic crystals from saturated solution is an important chemical process and plays a key role in the purification of pharmaceutical products.…”

Synthesis and Characterization of L-Alanine Sodium Bromide: A New Semi Organic Nonlinear Optical Material

“…In this stimulating context, organic nonlinear materials have been recognized as forefront candidate for fundamental and applied investigations involving, in a joint effort, chemists, material scientists and optical engineering [2 ,6 ]. Over past two decades, there has been remarkable interest in growth and characterization of nonlinear optical material crystals [5,8]. Second order nonlinear optical materials are used in optical switching, frequency conversion and electro-optical applications especially in Electro optical modulators [9,10].…”
