On the quartz plate, the edge rhombic boron nitride crystal with a density of just 1 to 3 microns is as slim as a cicada’s wing. Still, its power effectiveness is 100 to 10,000 times higher than that of conventional optical crystals. This is the thinnest recognized optical crystal on the planet created by Chinese scientists. At the opening ceremony of the 2024 Zhongguancun Online forum Annual Fulfilling hung on April 25, this crystal was released as a major accomplishment.
Academician Wang Enge of the Quantum Materials Science Facility of the College of Physics of Peking University, Professor Liu Kaihui of the Institute of Condensed Issue Physics and Materials Physics, and Hong Hao, a particularly appointed associate researcher, and various other scientists have developed a new crystal layout approach: by transforming each piece of rhombic boron nitride material at a particular angle like twisting a Rubik’s Cube, the stacked optical crystal can decrease the power usage of laser going through and effectively produce the required laser.

The crystal design theory originated by Chinese researchers is integrated with the prep work approach to effectively “slim down” the optical crystal to 1 to 3 microns. The thickness of standard optical crystals remains in the millimeter to centimeter level.
The r & d group summarized this approach as the user interface angle concept of two-dimensional products. “The application of this concept is expected to minimize the size of lasers to the micron level. Some products that were difficult to make optical crystals in the past are also anticipated ahead back to life by revolving the angle of product piling,” Liu Kaihui informed press reporters.
