EFFECTS OF SOME GROWTH CONDITIONS ON SHAPE AND LASER DAMAGE THRESHOLD OF KDP CRYSTALS

The effects of some growth conditions on KDP crystals were studied. It was found that the coordination ligand EDTA used in purification has no significant effect. Crystals grown from aged solution show much improved laser scattering condition and give higher values of laser damage threshold. The existence of poly phosphates seriously affects the growing habit of the crystals and decrease the laser damage threshold significantly.
