Study on the liquid inclusion induced light scatter in KDP crystal

Growth and properties of Ba‐doped KDP crystals

“…X. Sun et al [8] had discussed the formation of liquid inclusion induced light scatter in KDP crystal. They confirmed that some large dimension impurities such as EDTA, pyrophosphate, boric acid could be selective adsorbed on the (101) faces and resulted in higher density of scatter in pyramidal sector.…”

“…The recorded XRD patterns for the grown pure and Ba-doped KDP samples were shown in figure 3. The detection of scattering centers We utilize the ultra microscopy technique discussed in [8] to investigate the formation of scatting centers located in the bulk of KH 2 PO 4 crystals near characteristic crystalgrowth boundaries. The experimental setup is composed of a microscope with 50 x magnification powers, a laser operating at 532 nm 40 mW and a camera to capture the images.…”

Origin and relation of three kinds of scatter centers in KDP and DKDP crystals

“…For it can keep the lowest surface-energy. But its size is only from few nms to few tens of nms, which is much smaller than that of liquid inclusion reported in the literatures [10][11][12]. The other kind of scatter centers has similar shape with KDP (DKDP) crystals, and even the growth sector can be seen clearly.…”

“…The other kind of scatter centers has similar shape with KDP (DKDP) crystals, and even the growth sector can be seen clearly. Considering its size, it can be ascribed to inclusion in references [10][11][12], but it still can give some information about the formation of scatter centers. When the temperature is higher than the growth temperature, dissolution happens, and then the scatter centers form.…”

The rapid growth of large-scale KDP single crystal in brief procedure

“…Ultra-microscopy technique is used to investigate the formation of scattering found in the bulk KDP crystals [7]. The experiment setup is composed of a microscope with 50 Â magnification power, a laser operating at 532 nm and 40 mW.…”
