Fifty years after the invention of the laser, a team of scientists from Yale University (EE UU) has built the first AntiLaser world. The device absorbs the incoming laser energy and transforms light rays into electrical energy or thermal , says A. Douglas Stone, a researcher at Yale University (USA), told SINC Agency.
The mechanism, called "perfect consistency buffer (CPA for short in English), two laser beams focused to a specific frequency within a cavity that contains a disk of silicon semiconductor material. The hard lines of light waves that bounce off indefinitely until absorbed and converted into heat, as mentioned in Article published today in Science .

A laser backwards
Half a century after invention of the laser, "the AntiLaser runs a fundamental optical process that has not been studied until now," says Stone. It is, therefore, a laser that works in reverse: absorb light at specific frequencies instead of emitting . The device measures about an inch in diameter but scientists hope to build one of 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, the AntiLaser could aplicarseen the field of radiology , directing electromagnetic radiation to a region of human tissue opaque. In this way, we could obtain medical images or use the mechanism for therapeutic purposes.
