KDP Crystals Grown in Defined Crystallographic Direction

Abstract

KDP crystals are restrained to grow along (100) direction by a new designed platform. Compared to conventional method, it enables us to grow KDP crystals with higher optical utilization and less labor costs in fabrication process of optical components. The size of the grown crystals is 20×20×10mm3. Its quality has been analyzed by UV-vis spectral, chemical etching and high resolution X-ray diffraction. The FWHM of diffraction curves is 32 and 36 arc s. The transparency measured by UV-vis spectrometer is up to 80%. The results from various characterization studies indicate that the optical quality is almost as same as the conventionally grown crystals.
