, according to the daily mail of the UK, it looks like the latest weapon developed by American The Pentagon scientists, but it is actually the world's first "anti laser" developed by scientists, which can completely eliminate the exciting light.

scientists have recently developed the world's first "anti laser". It can completely eliminate the laser beam
laser can capture the incident laser beam, and force the laser beam to rebound around until the laser energy is absorbed. . The device is not used in the military field. At present, computer experts plan to use the device to create a new generation of faster optical computers.
the device can eliminate the laser beam, but it does not absorb the energy contained in the laser beam. Instead, it can transform the laser energy into heat, which means that soldiers attacked by laser weapons will still have serious bodily burns after using the device. It is reported that the anti laser is developed by Professor Douglas Stone (Douglas Stone) of the Yale University School of Engineering in the United States. He first proposed the concept of anti laser in the study last year. But at that time, his colleagues all regarded the concept of anti laser as a trifling matter, calling this technology a "backward development" of laser technology.
laser can produce coherent light, that is, a photon flow with the same frequency, amplitude and waveform. Researchers have said that they have developed a coherent light absorber, which is a silicon wafer that can capture and disperse the dry wave of predetermined wavelengths. In other words, if a laser generates a coherent light, the coherent optical full absorber can fully absorb the coherent light and thus eliminate the energy that may produce heat.
the Yale University research group says the anti laser operates at a special frequency, and when the wavelength changes, the device starts and closes. Theoretically, the laser can eliminate the laser 99.999%, but because of the limitation of the anti laser and silicon wafer, it actually eliminates 99.4% of the laser.
the only problem with the device is that it does not prevent damage from laser weapons. Professor Stone said: "laser energy will dissipate in heat. Therefore, if someone is burned by a laser weapon, the anti laser will not prevent burns. "
at present, the new generation of computers focus on the use of optical components instead of electronic components. The anti laser can provide important optical conversion and make the computer run faster. Ma Lin Sol Djassi (Marin Soljacic), a physicist at the Massachusetts Institute of Technology, said in an interview with the magazine that it was a very novel and amazing device.
