Random Anti-Laser tagged posts

Scientists have found a way to build the ‘opposite’ of a laser – a device that absorbs a specific light wave perfectly. This can be done even in complicated systems, in which waves are scattered randomly, and has many technological applications.

At TU Wien (Vienna), a method has now been developed to make use of this effect, even in very complicated systems in which light waves are randomly scattered in all directions. The method was developed in Vienna with the help of computer simulations, and confirmed by experiments in cooperation with the University of Nice. This opens up new possibilities for all technical disciplines that have to do with wave phenomena. The new method has now been published in the journal Nature.
