“…However, the crystal size is relatively small. For a large‐sized KDP crystal, the rapid growth method is usually used, in which the crystal is grown on a point seed in a highly supersaturated KDP salt solution . The formation of inclusions is the main issue in the rapid growth of KDP crystals.…”

Numerical simulations are performed to study the rapid growth of potassium dihydrogen phosphate crystals with a designed stirring paddle. The paddle is expected to produce a downward flow and enhance mass transfer near the crystal surface. The effects of rotation rate and crystal size on downward flow speed are investigated. As the rotation rate and crystal size increase, the downward flow speed increases linearly. The mass transport in the turbulent boundary layer is analyzed, and the surface supersaturation is calculated theoretically. The solute supply can be guaranteed by controlling the rotation speed of the stirring paddle during crystal growth.

“…1 Good quality, large-sized crystals of KDP in pure as well as with suitable dopants or functional groups have been grown by various techniques for device applications. [2][3][4] Recently, the study on dual laser beam separation technology and crystallization behaviour of KDP was reported. 5,6 Materials with fast processing, data transmission, frequency doubling, fast and high data storage capacity and data retrieving are in high demand in the modern society and this has made it necessary to grow good quality single crystals with high NLO and unique optical properties by adding some suitable dopants or functional groups.…”

In the present work, the authors have grown the bulk-sized single crystals of pure (Size ~ 45 × 10 × 10 mm 3 ) and first time L-threonine (LT)-doped (Size ~ 85 × 10 × 8 mm 3 ) KDP with high quality by Sankaranarayana-Ramasamy (SR) method in an aqueous solution at constant temperature. A remarkable enhancement in the growth rate was observed from 3.2 mm/day (pure) to 6 mm/day (LT doped), respectively. The crystal structure, lattice parameters and growth direction were confirmed by powder X-ray diffraction analysis. FT-IR study confirms the presence of L-Threonine doping in KDP. Further, the vibrational modes and surface morphology was studied by FT-Raman spectroscopy along with etching treatment and shows remarkable reduction of surface defects. The optical transparency of SR-grown KDP crystals was found to be enhanced from 76 to 88% due to LT doping. The optical band gap was calculated for both the crystals and found to be 5.68 and 5.53 eV. Crystalline perfection of the grown crystals was assessed by high-resolution X-ray diffraction, dielectric and wet chemical etching studies and found to be good. The obtained result shows that the grown crystals can be used for laser applications.

“…Potassium dihydrogen phosphate (KDP) crystal is an important optic-electro material developed in 1940s and has been widely used in various laser systems to control the frequency multiplication [1][2][3][4] and optical switching [5,6] due to its good non-linear optical properties and high laser damage threshold. In particular, KDP crystals have become the unique crystal that can be used in Inertial Confinement Fusion (ICF) [7] because it can be grown into large-scale size.…”
