Fifty years after the invention of the laser, a team of scientists from Yale University (USA) has built the first AntiLaser the world. The device absorbs the incoming laser energy and transforms light rays into electricity or heat, says A. Douglas Stone, a researcher at Yale University (USA), told SINC Agency.
The mechanism, called "buffer perfect consistency (CPA for short in English), two laser beams focused to a specific frequency within a cavity that contains a disk of silicon as semiconductor material. The hard lines of light waves that bounce off indefinitely until it is absorbed and converted into heat, as mentioned in Article published today in Science.
A laser backwards
Half a century after the invention of the laser, "the AntiLaser runs a fundamental optical process had not been studied until now, "says Stone. It is, therefore, a laser that works in reverse: absorb light at specific frequencies rather than emitting it. The device is about one centimeter in diameter, but scientists hope to build a only six microns. For now, the AntiLaser absorbs 99.4% of incoming light, but should be able to absorb 99.999%.
The next generation of computers, known as "optical" could use this new technology in switches, sensors and various components. In addition, AntiLaser could be applied in the field of radiology, to direct the electromagnetic radiation to a region of human tissue opaque. In this way, we could obtain medical images or use the mechanism for therapeutic purposes.
