  ILLUMINA-T the new high-power laser-communication system can improve and make satellite communication more powerful.

ILLUMINA-T laser system uses ground-based lasers-communication tools, aimed at targets by using orbital mirrors. Laser communication systems are not so easy to jam as radio waves. Laser rays can be used as a very high-secure communication tool. In some visions, the hollow laser ray covers information carrier laser rays. Because information carriers are traveling in the hollow laser ray, stealing information is very difficult. 

If somebody tries to push some sensor through the outer laser ray the system sees changes in the power of that protecting laser ray.

That means they see if somebody tries to steal information by eavesdropping messages. And that makes laser communication secure. 

 In some versions, laser ray protects the radio maser beam in that channel. That allows the system to communicate through the wall. 

The limits of the regular laser rays are that they cannot travel through walls without making holes into the walls. This is why there is lots of research about X- and gamma-ray lasers. Those lasers can transport information through walls without harming it.

But similar technology that is used in ILLUMINA-T can be used in laser weapons. The difference between laser communication and laser weapons is the energy ray's power. In some space-weapon models, ground-based high-power megawatt-scale laser systems send their laser rays to the mirrors at the orbiter.

The power of those laser rays would be high enough that they destroy satellites. In those weaponized models, the laser system is static, and the mirrors at the exhaust tube in front of the mouth of the laser aim the laser rays into mirror satellites. 

If those lasers are positioned in an X-shape formation those mirrors can cover 360-degree areas. The same lasers can be used as the message lasers, and if the system must use them as weapons they must just adjust their power to a destructive level. The most powerful lasers can produce over 2000 terawatt power. 

That power will break those laser mirrors immediately. But it is possible. These kinds of ultra-powerful lasers can be dangerous also for ground targets. 

Even if orbital mirrors are single used in that power level they still have time to aim laser ray into the target. If a 2000 terawatt laser system shoots its beam through the orbiter, it could destroy at least high-flying aircraft. The laser weapon can also as a scientific tool, and only if that weapon is needed the operators can put the mirrors in the right points and those laser rays can conduct out from the laboratory by using channels that are made for that purpose. 

Researchers are making artificial solar flares by using high-power lasers.

The purpose of the new high-power lasers is to research a thing called magnetic reconnection. The idea of the system is that high-power lasers can form miniature flares. 

"Magnetic reconnection is when two anti-parallel magnetic fields—as in two magnetic fields going in opposite directions—collide, break, and realign. As innocuous as it sounds, it is far from a calm process". (ScitechDaily.com/Unlocking the Secrets of the Universe: Researchers Use High-Powered Lasers to Study Magnetic Reconnection). 

"This phenomenon is seen everywhere in the universe. At home, you can see them in solar flares or Earth’s magnetosphere. When a solar flare builds up and appears to ‘pinch’ out a flare, that is magnetic reconnection,” explains Taichi Morita, assistant professor at Kyushu University’s Faculty of Engineering Sciences and first author of the study. “Auroras are formed as a result of charged particles expelled from the magnetic reconnection in Earth’s magnetic field.”  (ScitechDaily.com/Unlocking the Secrets of the Universe: Researchers Use High-Powered Lasers to Study Magnetic Reconnection). 

Chemical bonds are also a magnetic phenomenon. The system can research when the chemical and magnetic bonds between particles are breaking when the energy level rises. And then the system can research can those broken forms reconnect. When the energy level in molecules increases. 

That thing causes oscillation. And when oscillation turns high enough it breaks the physical bonds between particles. Or actually when particles' energy level increases. Their quantum field turns larger. When the energy pumping ends. That thing decreases the size of the quantum fields. '

And the distance of the particles increases. That thing also breaks chemical and physical bonds. But the question is does the increase in energy level break those bonds, or would that happen when the energy level decreases? 

Another interesting thing is which point of the atom or electron makes the bond. What is the perfect position of an electron for making those bonds? If there is a certain position where the electrons can form the chemical bonds that thing allows the creation of molecules by using a minimum energy level. 

Magnetic reconnection could be a useful tool in nanotechnology and in materials or molecules that are repairing themselves. But the high-power laser systems can also bring data on how to predict solar winds. 

The use of high-power lasers for creating miniature solar flares is an interesting thing. The high-power lasers and very high-energy plasma can tell about the energy flow in very hot or high-energy environments. And that thing can tell about the conditions where the space weather turns hostile. If the solar wind from the sun turns very high it can cause problems for satellites. 

Solar wind means the protons and other particles that the sun sends to space. And those high-energy particles can destroy or damage satellites very easily. High-energy particles can destroy electronics or they can deny communication in the orbital trajectory. The high-energy plasma can also deny the use of radar satellites or radio-based communication. 

In the case, where the high energy particles are denying radio communication satellites must turn to the use of laser communication. But the problem is the impact of those particles. So by using magnets that are far away from the satellite is possible to turn the direction of the high-energy particles. 

And the satellites can also load with positive electricity just like in plasma brakes. But in that case, the purpose of that electric load is just to repel protons and other positive ions. If the number of impacts of those particles can decrease, that thing makes it possible to protect components against high-energy particles. 

If a satellite collects electrons from Van Allen's belts. That kind of system can collect energy for small-size satellites. Collecting energy from the plasma belt is theoretically quite an easy thing. The satellite must just put an antenna to the plasma. And that inducts electricity to its circuits. That kind of system can be a useful replacement for solar panels in the cases of small-size recon satellites.
