Has developed the world's first anti-laser pointer
The research team published a theoretical research result on anti-laser. Studies have shown that the laser pointer beam of a specific frequency enters the container containing the "lossy medium" of the silicon chip. The silicon chip can perfectly capture the light beam. The captured beams will move back and forth in the container irregularly until they are completely absorbed and converted into heat energy. This proves that the anti-laser can use the most common semiconductor material, silicon, as the "loss medium" to capture the laser beam. It claims to have developed the world's first anti-laser. They call it a coherent perfect absorber. Currently this device can absorb 99.4% of the incident laser beam. Theoretically, the anti-laser can absorb 99.999% of the incident beam. But due to experimental conditions. Now it can only absorb 99.4% of the incident beam.

Wavelength
The equipment we developed is just a proof of concept. But I believe that with the advent of more and more advanced anti-lasers. We will gradually break through this theoretical limit. "Similarly, the width of the anti-laser developed by this team is 1 cm, but Stone said that the computer has simulated the method of making a 6-micron wide (approximately one twentieth of the average width of a human hair) anti-laser. Currently. Countries all over the world are working on anti-laser research. For example, Stefano Longi of the Politecnico di Milano, Italy’s "Physical Review A". He once introduced the method of integrating laser and anti-laser in the same device.
