Intense Laser Experiments Provide First Evidence That Light Can Stop Electrons

Intense Laser Experiments Provide First Evidence That Light Can Stop Electrons

While conducting experiment scientists came to remarkable evidence which showed that light can stop electrons in its track. While administering their ultra-intense laser research it as was found that hitting the electrons opens up a treasure trove which simply goes beyond the things established by the classical physics. In other words we are talking about the exquisite realm of the quantum physics the quantum effects which can be brought upon the electrons with this research.

Unlocking the mysteries

It is worth noting that when a light hits the object then a small of the light happens to be getting scattered upon touching the surface of the object. But when the object is moving at incredible fast pace and the also happens to be extremely intense then strange things occur. Electrons are also known to radiate wide amount energy and shaking them violently helps I slowing down their pace. This very process is known as the radiation reaction. Finding the way top where light can stop electrons are simply been a baffling experience for the researchers.

The radiation reaction has been known to happen only to the objects which are closer to the black holes as well as such black holes which are surrounded with the disc of gases. It has never been possible to look or measure the radiation reaction in the lab conditions but this very experiment has help scientists in getting insight into this remarkable process right within their labs.

Making the intense light

One of the scientists associated with this research has stated that it is extremely important for us to test out the theoretical predictions as it helps in learning new things. The experiments done by them are being based on the theory laid out for the high intensity laser research but it has led them into the quantum domain.  Though the fruits of the first few experiments should not be take a definite success that the light can stop electrons but further study and experiment has to be done to dig deeper. Scientist will be making useof the even higher energy electron beams in theirexperiments in the days to uncover the mysteries surrounding it.

In one such experiment this team has been successful in making the light extremely intense by focusing it on a single yet small spot. Herein they were able to delivering all the nascent energy for a short amount of time of 40 quadrillionths of a second.  Researchers had made of unique technique called ‘laser wakefield acceleration’ in order to create such an electron beam which is small enough to interact with any focussed laser beam with ease.

Using this technique scientist has also fired another intense laser pulse with the gas which helped in turning the gas into the plasma. It was found that the electrons were able to surf on this deadly plasma at the same time building up high energies by travelling just a short distance. From understanding that light can stop electrons scientists have a long way in the course of their experiments and the future will help in unlocking may more mysteries.
