Scientists build world's first anti-laser
More than 50 years after the invention of the laser, scientists at Yale Univ. have built the world's first anti-laser, in which incoming beams of light interfere with one another in such a way as to perfectly cancel each other out.
After more than a decade of work and $3.5 billion, US engineers have completed the world's most powerful laser, capable of simulating the energy force of a hydrogen bomb and the sun itself.
