With a total of 3 patents, his work is crucial for advancements in laser technology.

Latest Patents

One of his latest patents is titled "Method for growing long-seed DKDP crystal by two-dimensional motion." This innovative method allows for the growth of crystals along a cylindrical surface, eliminating the low optical quality associated with cylinder-cone interfaces. By avoiding three flow regions that can lead to inclusion formation, the method ensures a uniform hydrodynamic environment, which enhances the growth velocity and stability of the crystal morphology. This technique is particularly beneficial for the large-size, high-quality DKDP crystals required by ICF laser devices.

Another notable patent is the "Method for rapid growth of long seed KDP-type crystals." This pyramidal growth method restricts the lower end of the long-seed crystal while allowing the upper end to grow freely into a pyramidal shape. The simultaneous growth of four prismatic faces minimizes growth stress and ensures high optical quality in the cut optical elements. The use of blade-like stirring paddles during the growth process further enhances the optical uniformity of the crystals.
