Growth and characterization of amino acid based nonlinear optical single crystals of organic and semiorganic compounds

Abstract

Nonlinear optical NLO frequency conversion materials have newlinesignificant impact on laser technology optical communication and optical newlinedata storage technology The search for novel and efficient nonlinear optical newlinematerials has been an active area of research since second harmonic newlinegeneration was first observed in single crystal quartz by Franken and coworkers newlinein 1961 Applications such as frequency conversion light amplitude newlineand phase modulation and phase conjugation await further advances in newlinematerials particularly new crystals A good NLO crystal must satisfy the newlinefollowing five basic conditions a a large NLO effect b a high optical newlinedamage threshold c high optical homogeneity d appropriate transparent newlinewavelength range and e good physicochemical properties newline newline newline
