Latest Patents

One of Changzhang Chen's latest patents is titled "Doped low-temperature phase barium metaborate single crystal, the manufacturing method thereof and wave changing elements therefrom." This invention focuses on the growth method of doped low-temperature phase barium metaborate single crystals using the molten salt method. The single crystal developed through this method addresses the shortcomings of traditional barium borate (BBO) crystals, which are known for their strong deliquescence. The new crystal exhibits almost no deliquescence, significantly improved frequency doubling effects, and a higher optical damage threshold compared to BBO. Additionally, it has enhanced hardness, with a Shore hardness of 101.3 and a Mohs hardness of 6, compared to BBO's Shore hardness of 71.2 and Mohs hardness of 4. The transmittance curves from UV-Vis region tests indicate a cut-off wavelength of 190 nm and an absorption onset wavelength of 205 nm. This innovation is widely applicable in laser and nonlinear optics, particularly in frequency conversion for ultraviolet and deep-ultraviolet applications.
