Embodiment Construction
[0022] Realize the specific embodiment of the present invention Preferred scheme 1: the growth of KDP crystal
[0023] Optically pure KDP solution was prepared by using high-purity raw materials, about 2 kg of fast-shaped crystals were crystallized, and 10000 mL of optically pure KDP solution was prepared. The saturation point of the solution was determined to be about 60°C by hanging crystal method. Filter and purify the solution with 0.15 μm filter paper. Bind 60×60×2mm on the crystal carrier 3 KDP crystals were used as seeds.
[0024] The interlayer between the insulation lower layer and the growth cylinder is filled with distilled water. The growth chamber in the growth tank is filled with KDP solution with a saturation point of about 60°C, and the volume is 10000ml. Heat the water bath to 75°C, overheat for about 12 hours, put 2 kg of KDP crystal raw material in the dissolution chamber at a temperature 2°C higher than the saturation point, and put in the seed crystal,...
