Chinese researchers announce that they have succeeded in developing a brand new technology allowing the use of a laser which might well revolutionize anti-aircraft defense.
Lasers are sometimes used as weapons, especially to destroy drones during conflicts. However, this technology has limits because the material overheats (Overheating is a physical operation that takes place in a steam engine.) very quickly, which reduces its use. Indeed, when the laser (A laser is a device that emits light (electromagnetic radiation)…) is found in the air (Air is the mixture of gases that make up the Earth’s atmosphere. It is odorless and…), the gas (A gas is a set of very weakly bonded atoms or molecules and…) that it encounters on its way heats up so much that it endangers the material itself. After each use, a cooling time is thus necessary.

Concretely, the laser works thanks to a ray of light which is produced using atoms (An atom (from the Greek ατομος, atomos, “that we cannot…). These are excited by various methods and are then exposed to a photon (In particle physics, the photon (often symbolized by the letter γ — gamma)…), which instantly deexcites them and generates a particular phenomenon: the atoms begin to produce themselves a photon similar to the one that hit them. And so on, this phenomenon is repeated until a laser is formed. This laser is then amplified using lenses and mirrors in order to cause an energy (In common sense energy designates everything that makes it possible to carry out work, manufacture important…) However, this technology presents problems of overheating If heat (In everyday language, the words heat and temperature often have an equivalent meaning:…) is not correctly managed, the concentrated emission of light can cause internal damage, alter the components and thus reduce the performance of the laser or even render it unusable.
Researchers at the National University of Defense Technology in Changsha report that they have succeeded in drastically reducing heat emission, which might allow continuous firing like the world or…) by opening the possibility of using a much more powerful laser than those used to date (The day or the day is the interval which separates the sunrise from the sunset; it is the. ..). To achieve this, the team succeeded in inserting a specific gas into the barrel which would be blown directly into the laser chamber. The excess heat would then be captured and evacuated in real time, which would avoid this major problem.
This is a major breakthrough, a first in the history of laser research in China. Applications might be envisaged, in the military field, but also industrial.
