Abstract

Potassium dihydrogen phosphate (KDP) crystals grown along the type-II phase-matching direction were investigated for crystalline and optical perfection. Highresolution X-ray diffraction (HRXRD) technique was used for investigating crystalline perfection. UV–VIS transmission, Mach–Zehnder interferometry, birefringence interferometry and conoscopy were performed for optical characterization. HRXRD results show that the grown crystals have good structural perfection. A uniform transmittance of 92% was observed in the visible region of the spectrum. Straight and parallel fringes were observed in Mach–Zehnder interferometric studies. A symmetrical fringe pattern was obtained in conoscopy images. These interferometric results suggest that the optical homogeneity of the grown crystal was good and not influenced by the growth technique
