“…The XRD study indicates that the SR KDP crystal has good crystalline perfection compared to conventional KDP crystal. These conclusions are relatively consistent with Ramasamy's works [6,7,8,9] and Barati's work [17].…”

“…Ramasamy et al [6,7] reported the KDP crystals grown by the SR method had damage thresholds higher than the conventional method grown crystals. The damage threshold was influenced by the dislocation in the KDP crystal, and the crystal with many dislocations presented low damage threshold [8]. These conclusions showed that the quality of the crystal grown by the SR method is better than conventional method grown crystal for optical device [9].…”

Potassium Dihydrogen Phosphates (KDP) crystal has been studied since the early 1930s. It has many important applications, such as the electro-optic modulator, Q-switches, the ultrasonic transducer, the shutter for high-speed photography, frequency doubling and high power laser frequency conversion for fusion research. In response to these applications, the highquality KDP single crystals are required. The common method of KDP crystal growth is the lowering of the temperature of saturated KDP solution which is held in a cylindrical tank. The disadvantage of this method is the spontaneous appearance of crystalline clusters at the bottom of the tank which retard the growth of the main crystal. Since the 2010s, Sankaranarayanan and Ramasamy have proposed a new method of growing crystal by designing the Y-shaped solution tank. In this study, the KDP single crystals were grown by the Sankaranarayanan-Ramasamy (SR) method. These crystals have better quality, fewer defects, higher hardness and density, and especially material saving compared to ones from the conventional method.

“…Negres et al concluded that the LID density has a distinct aggravation near the PY–PR boundary compared to other sectors of a “point-seed” rapidly grown KDP crystal. To avoid the formation of PY–PR boundaries during the rapid growth of KDP-type crystals, the Sankaranarayanan–Ramasamy (SR) method was proposed. , Although there is no PY–PR boundary in the crystals grown by the SR method, , the flow conditions of the solution in this method are worse than that of KDP crystal grown on a rotating platform, − making it difficult to grow large-aperture KDP-type crystals.…”

The pyramid−prism interface in "point-seed" rapidly grown DKDP (KD x H 2−x PO 4 ) crystals affects the quality of tripler-cut samples used in inertial confinement fusion devices. In this study, a cuboid DKDP crystal without a pyramidal sector was rapidly grown. The quality of the cuboid DKDP crystal was evaluated by measuring the deuterium homogeneity, crystalline quality, transmission spectrum, and laser-induced damage performance. The total number N of tripler-cut samples that can be obtained from the cuboid DKDP crystal is easily calculated. The size of the tripler-cut sample is approximately equal to the cross-section of this cuboid DKDP crystal. Moreover, as this cuboid DKDP crystal has a regular shape, calculating the mass of the crystal and accurately controlling the supersaturation of the solution during growth is easy. The successful crystal growth using this proposed approach establishes the possibility of growing large-aperture cuboid DKDP crystals. Currently, research on the rapid growth of a cuboid DKDP crystal with an aperture of more than 40 cm is underway.Article pubs.acs.org/crystal
