. A powerful laser, the brightness of which is about a billion times the brightness of the Sun helped American physicists to see how one electron is faced with thousands of particles of light, and reveal the unusual nature of their interaction with each other, according to a paper published in the journal Nature Photonics.

«When we are dealing with a super-bright lasers, light scattering is a fundamental process by which we see the world around us is radically changing. These changes can be represented as if the shape of the objects would be changed when increasing or decreasing the brightness of the bulb. The object is not easy to become brighter or darker — the light are reflected at different angles, with different colors when the brightness changes,» says Donald Umstadter (Donald Umstadter) from the University of Nebraska-Lincoln (USA).

As a rule, the collision of the photon and electron leads to the fact that the photon bounces and starts to move in the opposite direction, without changing of its frequency and other physical properties. The operation of this rule, which physicists call Romanowski scattering, scientists have repeatedly confirmed, watching the processes in space and in laboratory experiments, where single particles of light are faced with isolated electrons.

Umstadter, and his colleagues decided to test what happens if you push one electron with hundreds or thousands of particles of light that slam into him at the same time. The realization of this task is not as simple as it may seem initially: the photon and the electron are ultra-small particles, the collision of which is highly unlikely situation.

For example, when room lighting lamp or other normal conditions, the electron collides with a particle of light just once in four hours, and virtually never occurs with two or more photons simultaneously.

Experiments showed that the behavior of electrons and photons sharp change in these conditions. The carriers of electric charge are converted from points to a kind of «g» and the «loop» and photons start to «break» the laws of physics and bounce off of electrons is not so, as the theory predicts Thomson. For example, the angle of reflection of the photons, their frequency and some other parameters begin to depend on how bright was an impulse containing them.

Moreover, the unusual behavior of electrons in these situations allows them to be used for «gluing» a large number of low-energy particles of light into a single high-energy photon. To demonstrate scientists have connected 500 particles of light from the infrared range in a single x-ray photon.

Using this effect, physicists have a clear three-dimensional pictures of the memory chips from a normal USB stick, not with a heavy-duty particle accelerators, which are commonly used for such purposes. The same technology, according to Umstadter can be used for medical experiments and observations, and to accurately measure the power of laser beams.
