Physicists have created a laser, the beam of which is able to pass through the white walls

A team of scientists led by Hui Cao from Yale University examined what fraction of the beam's photons

seeps through dense matter, which does not absorb, but reflects light.

To do this, physicists have developed twoultrasensitive matrices installed on sheets of compressed zinc oxide nanoparticles, which played the role of this wall, began to monitor how much light passes through its different sections.

Scientists have used for these experiments an optical device - a spatial light modulator. With it, you can flexibly control the spatial structure of the beams of electromagnetic waves.

As a rule, any optical beam falling intoscattering medium, such as fog, begins to spread in lateral directions. We found out: the laser beam can be prepared in such a way that it will only move forward through it.

Physicists during the experiment managed to setspatial modulator such a form of the beam, that he began to pass through opaque objects. To do this, its structure should be made similar in width to the channels between atoms and electrons, where light can move freely.

As a result of the experiments, the laser beam began to scatter less, and its power increased by 4.5 times.
