Abstract
Organic non-linear optical materials receive much attention owing to their very large second order nonlinearities, ultra-fast response times and high optical damage thresholds. In the present work, low temperature solution growth technique has been employed to grow non-linear optical hippuric acid (HA) C 6 H 5 CONHCH 2 COOH single crystal with dimensions 10 x 6 x 3 mm 3 were obtained in a period of 18 days using acetone as solvent. Powder XRD analysis reveals that the crystal belongs to an orthorhombic system with space group P2 1 2 1 2 1 and lattice parameters were found to be a = 8.8514 A, b = 9.0842 A, c = 10.5807 A. UV optical absorption analysis on these samples reveals the transparency of the crystal in the visible region. The bonding structure and molecular associations due to chemical reactions were analyzed by FTIR spectroscopy.

Summary
Coherent radiation from common lasers can be converted to any other desirable wavelengths using nonlinear optical (NLO) effects by means of NLO crystals. The nonlinear optical (NLO) organic materials have been the subject of extensive theoretical and experimental investigations during the past two decades [1,2]. Nonlinear optics (NLO) has wide applications in the field of telecommunication and information devices [3,4,5,6]. Nonlinear optics is playing a major role in the emerging photonics and optoelectronics technologies. New non linear optical frequency conversion materials have a significant impact on laser technology, optical communication and optical data storage [7,8,9]. Organic NLO materials are attracting a great deal of attention for possible use in optical devices because of their large optical non linearity, low cutoff wavelength, short response time and high threshold
