Single crystals of glycine doped potassium dihydrogen phosphate have been grown by slow evaporation solution technique, slow cooling along with seed rotation and Sankaranaryanan-Ramasamy method. The size of the grown crystal in slow cooling method was 35x25x20 mm{sup 3} and in SR method it was 20 mm in diameter and 110 mm in length. The grown crystals were characterized by HRXRD, UV-Visible, dielectric, Vickers microhardness, laser damage threshold and SHG studies. The crystalline perfection of the grown crystals has been analyzed by high resolution X-ray diffraction. The transmittance of the grown crystals is 66%, 70%, and 77% respectively and all the crystals have good transparency in the entire visible region. The crystal grown by SR method glycine added KDP has much higher hardness value than other method grown crystals. Higher laser damage threshold was observed in SR method grown glycine added KDP crystal compared to SR method grown pure KDP crystal. The second harmonic generation efficiency of the glycine doped KDP is increased compared to pure KDP.
