Organic materials are expected to have relatively strong nonlinear optical properties due to delocalized electrons at * orbitals. This expectation explains extensive search for better NLO materials among organic crystals. ==L-arginine maleate dihydrate (LAMD)== L-Arginine is one of the essential amino acids widely distributed in biological substances. It forms a number of salts with organic and inorganic acids showing non-linear optical properties. L-Arginine maleate dihydrate (LAMD, C6H14N4O2,C4H4O4,2H2O) is one of these L-arginine salts which is a complex of strongly basic amino acid, carboxylic acid and provides useful information in relation to molecular interaction in present day biological systems and to prebiotic self-organisms.〔S.L. Miller, E.L. Orgel, "The Origins of Life on the Earth", Prentice- Hall, New Jersey, 1974.〕 It is also a nonlinear optical material with second harmonic generation efficiency 1.68 times that of KDP.〔"Synthesis, crystal structure and solubility of C6H14N4O2,C4H4O4,2H2O" (Sci. Technol. Adv. Mater. 6 (2005) 508 ) (''free download'')〕 LAMD crystals are grown from solution by solvent evaporation; they belong to the triclinic space group P1. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Organic nonlinear optical materials」の詳細全文を読む スポンサード リンク
