Gas Act - evaporation or volatilization of crystalline materials, including chemical vapor deposition and RF sputtering are two ways. The basic principle of the aqueous solution of raw materials (solute) dissolved in water, take appropriate measures to cause the solution supersaturation, the crystal in which the growth. Figure 3-1 in aqueous solution using the cooling method of crystal growth device, mentioned earlier, potassium dihydrogen phosphate (KDP), two deuterium phosphate potassium (of DKDP) crystals is to use the growth of such a device. KDP crystal nonlinear coefficient is small, easy deliquescence and other shortcomings, but it is easy to grow, can meet the large size of the laser nuclear explosion simulation requirements. Thus far, can be used in high power systems for laser fusion research in the crystal, only of KDP. The laser pointer workshop improves requirements of workshop management.
The hydrothermal method is a high temperature and high pressure crystallization from supersaturated aqueous solution. Industrialized bulk growth of crystals using this method. Crystal growth in a specially designed autoclave, crystalline materials on the bottom of the autoclave, solvent added to the kettle. Heated to a certain temperature difference between the upper and lower solution, convection, and the bottom of the high-temperature saturated solution with low temperature seed the formation of supersaturation and crystallization. Americans are the initial growth of KTP crystal line degree about 10mm, 800 ℃ in the 3000 atmospheric pressure in the inner diameter of only 38mm autoclave growth. KTP crystal nonlinear coefficient, light transmission band width, and chemical stability, excellent mechanical properties, is a very good performance of nonlinear optical crystal. The customer asks for the strict inspection for this kind of laser pointer .
The United States has a long time, the KTP crystal as the quartermaster substances under the control of the Congress, an embargo on China. Temperature solution method in the unremitting efforts of the scientific and technological workers in China, the successful growth of high optical quality, large size of the KTP crystal, breaking the monopoly of the United States and sold back to the United States to win the honor for the country. U.S. scientists need Z slices of 20 × 30mm2 KTP crystal waveguide experiment, but they KTP crystal growth can only be cut out 8 ~ 9mm the size of the Z slice, so he had in the international search for the large size of the KTP crystal, and ultimately found that China's artificial Crystal Institute KTP crystal growth to meet their needs had to be imported from China. laser pointer is in the direct charge of Vice Chief Engineer.
