Linear and Non Linear Optical Properties of L- Alaninium Malate (LAM) Single Crystal an Efficient Organic NLO Material

Amino acid family of materials is uitable for Non Linear Opticalaplications due to Zwiter ionic and chiral nature of its molecules. L alanine family of crystals has high optical transmitance in the whole visible range. The optical band gap (E ) vs h was determined by extrapolating the linear egion of the curve to the h ) such as Extinction coeficient, Reflectance, Refractive index, Complex dielectric constant, and Optical conductivity are calculated for the grown crystal and its variation with incident photon energy is analyzed. Second Harmonic Generating (SHG) eficiency of the candidate material was determined by Nd:YAG Q-switched laser Kurtz powder technique and its 1.1 times greater than KDP.
