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 power efficiency is 100 to 10,000 times higher than that of typical optical crystals. This is the thinnest known optical crystal worldwide invented by Chinese scientists. At the opening event of the 2024 Zhongguancun Online forum Annual Satisfying held on April 25, this crystal was launched as a significant achievement.

Academician Wang Enge of the Quantum Materials Science Facility of the Institution of Physics of Peking College, Professor Liu Kaihui of the Institute of Condensed Matter Physics and Materials Physics, and Hong Hao, a specially selected associate researcher, and other researchers have developed a brand-new crystal design method: by turning each piece of rhombic boron nitride material at a specific angle like twisting a Rubik’s Dice, the piled optical crystal can lower the power intake of laser passing through and efficiently produce the needed laser.

The crystal layout theory originated by Chinese researchers is integrated with the prep work method to effectively “slim down” the optical crystal to 1 to 3 microns. The thickness of traditional optical crystals remains in the millimeter to centimeter degree.

The research and development group summarized this technique as the user interface angle theory of two-dimensional products. “The application of this theory is expected to minimize the dimension of lasers to the micron level. Some products that were difficult to make optical crystals in the past are likewise expected ahead back to life by revolving the angle of product stacking,” Liu Kaihui told press reporters.
