DKDP (KDxH2-xYES4), Which can reduce Raman-stimulated Raman scattering, is the best nonlinear crystal used as a tripartite inertial framework (ICF) lens.
It takes one to two years for a DKDP to receive ICF facilities using the traditional growth method. Therefore, the rapid growth method is valid. However, in fast-growing DKDP crystals of "seed dots", all prismatic faces and pyramidal faces grow under highly saturated solutions, forming a so-called pyramid-prism (PY-PR) boundary that is detrimental to the enhancement and enhancement of frequencies. .
Recently, researchers at the Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences (CAS), have successfully grown large seed DKDP crystal size 470 mm × 495 mm × 560 mm.
With a 320mm long seed, the DKDP crystal grows in just three months. And this crystal can remove DKDP travelers that do not contain the PY-PR border.
The long-seeded DKDP crystal not only takes advantage of the traditional method without the PY-PR border, but also has the advantage of a fast-growing "seed-point" method with a high growth rate. At the same time, it can also improve travel efficiency for travelers.
This is the world's first large seed DKDP crystal, indicating that the rapid growth of long seeded DKDP crystal has been successfully verified. And this is a new scheme of the DKDP crystal growth method provided for the construction of ICF facilities.
The long-seeded DKDP crystal grows from a self-developed device captured with a continuous filtration system at SIOM. The related crystal growth method and self-developed device are patented.
