A system is reported for evaporation-controlled crystal growth of potassium dihydrogen phosphate (KDP) from aqueous solution by the Sankaranarayanan−Ramasamy (SR) method. KDP (KH2PO4) single crystals of 10-, 20-, and 40-mm diameter and 60-mm height have been grown at an average growth rate of 5 mm/day from the point seed in a glass crystallizer. The growth rate formula is derived for the SR method. The grown crystals were characterized by UV−vis, laser Raman, second harmonic generation efficiency, and laser damage threshold studies. The SR method is an efficient method to grow crystals of good optical quality.

“…In such powerful facilities designed to reach ICF (Inertial Confinement Fusion), optical components are submitted to laser illuminations that may lead to damage and decrease their performances. Due to the dimensions required, KDP used in LMJ and NIF are specifically sliced from boules obtained by rapid growth techniques (a 50x50x50 cm 3 crystal is obtained in two months [1]). Theses techniques induce new issues between conventionallyand rapidly-grown KDP, although it has been shown that there is no difference (in terms of material property [2]).…”

KDP crystal orientation influence on the nanosecond laser-induced damage at 1064nm

et al. 2010

We investigate the influence of THG-cut KDP crystal orientation on laser damage at 1064 nm under nanosecond pulses. This study makes a connection between precursor defects and the influence of their orientation on the laser damage. Previous investigations have already been carried out in various crystals and particularly for KDP, indicating propagation direction and polarization dependences. We performed experiments for two orthogonal positions of the crystal and results clearly indicate that KDP crystal laser damage depends on its orientation. We carried out further investigations on the effect of the polarization orientation, by rotating the crystal around the propagation axis. We then obtained the evolution of the damage probability as a function of the rotation angle. To account for these experimental results, we propose a model based on heat transfer, the Mie theory and a Drude model. The geometry of the precursor defects is assumed to be ellipsoid-shaped and we numerically introduce absorption efficiency calculations for this geometry. Modeling simulations are in good agreement with experimental results.
