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.^[1] It is also a nonlinear optical material with second harmonic generation efficiency 1.68 times that of KDP.^[2]

LAMD crystals are grown from solution by solvent evaporation; they belong to the triclinic space group P1.

L-methionine L-methioninium hydrogen maleate (LMMM)

LMMM too belongs to the amino acid family. Crystals are grown by slow evaporation of an aqueous solution containing L-methionine and maleic acid, resulting in centimeter-large crystals of a non-centrosymmetric space group.^[3] They were applied for second harmonic generation of an YAG laser (wavelength 1064 nm), and SHG efficiency equal to that of KDP has been obtained.
