The traditional laser has been turned inside out, producing what scientist like to call an “anti-laser”. This device is actually called a coherent perfect absorber and has the capabilities to absorb rather than release a stream of light.
In a traditional laser, energy is injected into a medium that is transferred between two mirrors while stimulating photons, which are then reflected back through the mirrors, resulting in an amplification of light. The anti-laser works in a similar fashion, except the medium contains an absorptions component instead of amplification one. Scientists believe the anti-laser has the potential to be used in fields such as computing and medical imaging; leading to instrumental advances in technology. This innovational physics device was discovered by scientist at Yale University and has been noted as a surprising and exciting achievement in the science community.
