On the quartz plate, the edge rhombic boron nitride crystal with a thickness of only 1 to 3 microns is as thin as a cicada’s wing. Still, its energy efficiency is 100 to 10,000 times greater than that of conventional optical crystals. This is the thinnest known optical crystal worldwide designed by Chinese researchers. At the opening ceremony of the 2024 Zhongguancun Discussion forum Annual Fulfilling hung on April 25, this crystal was launched as a major success.
Academician Wang Enge of the Quantum Products Scientific Research Facility of the Institution of Physics of Peking College, Teacher Liu Kaihui of the Institute of Condensed Matter Physics and Products Physics, and Hong Hao, a specifically appointed associate researcher, and other scientists have actually developed a brand-new crystal style approach: by turning each item of rhombic boron nitride material at a details angle like twisting a Rubik’s Cube, the piled optical crystal can reduce the power intake of laser passing through and effectively produce the needed laser.

The crystal style concept originated by Chinese scientists is combined with the prep work method to effectively “lose weight” the optical crystal to 1 to 3 microns. The density of standard optical crystals is in the millimeter to centimeter degree.
The r & d group summarized this technique as the interface angle theory of two-dimensional products. “The application of this concept is expected to lower the dimension of lasers to the micron level. Some materials that were difficult to make optical crystals in the past are likewise anticipated ahead back to life by turning the angle of material piling,” Liu Kaihui told reporters.
