On the quartz plate, the corner rhombic boron nitride crystal with a density of only 1 to 3 microns is as slim as a cicada’s wing. Still, its energy effectiveness is 100 to 10,000 times higher than that of standard optical crystals. This is the thinnest well-known optical crystal on the planet developed by Chinese scientists. At the opening event of the 2024 Zhongguancun Online forum Yearly Fulfilling hung on April 25, this crystal was launched as a major success.

Academician Wang Enge of the Quantum Materials Science Center of the School of Physics of Peking University, Teacher Liu Kaihui of the Institute of Condensed Matter Physics and Materials Physics, and Hong Hao, a specially selected associate researcher, and other scientists have produced a new crystal design method: by transforming each piece of rhombic boron nitride product at a particular angle like turning a Rubik’s Dice, the piled optical crystal can lower the power usage of laser passing through and efficiently create the required laser.

The crystal design theory pioneered by Chinese scientists is integrated with the preparation approach to effectively “slim down” the optical crystal to 1 to 3 microns. The density of standard optical crystals remains in the millimeter to centimeter level.

The r & d team summarized this method as the interface angle theory of two-dimensional materials. “The application of this concept is anticipated to minimize the size of lasers to the micron degree. Some materials that were difficult to make optical crystals in the past are additionally anticipated to come back to life by rotating the angle of material piling,” Liu Kaihui informed reporters.
