Light can control superconductivity.

"This light-induced superconductivity has been shown to replicate crucial features like zero electrical resistance and expulsion of magnetic fields, suggesting potential applications in high-speed devices and extending superconductivity to ambient temperatures."

Many materials reach superconductivity in very low temperatures. Things like UV- or IR lasers can adjust the temperature in the superconducting structures. That is one way to control the electricity in the superconducting 2- or 3D structures. The laser can switch superconductivity on and off. This helps the system control switches and gates in a microchip.

Superconducting computer systems are the most effective data systems in the world, but they need resistance to control some vital elements. The laser can warm resistors, gates, and switches. And the rest of the systems can superconduct.

Another thing that can cause superconducting of material is pressure. The laser systems can press material from both sides, making them superconduct at high temperatures. The high-pressure laser-based system can turn material superconducting when operators want. However, the problem is that laser systems require lots of energy.

Another thing is that. The laser-based superconductivity can be done only in small areas. The laser-base superconductivity can revolutionize the computing. The system can use this thing to adjust the systems like new 2D microchips. In 2D microchips, the microchip structure atom-size components that are on or in the 2D atom structure operate like full-scale systems.

The laser system adjusts resistance in that structure with extreme accuracy. And that thing can make the nano-size microchips work. The problem with nanotechnical microchips is temperature. Superconductivity can be the answer to that problem.

However, the main problem with superconducting microchips is controlling the electric flow in microchips. There is always the possibility that the information jumps over gates and switches. And if the system can switch superconductivity on and off, that makes it fundamental and effective.

MIT's tractor beam can make the new types of SASER systems possible

"This chip-based "tractor-beam," which uses an intensely focused beam of light to capture and manipulate biological particles without damaging the cells, could help biologists study the mechanisms of diseases."(Interesting Engineering, MIT’s Star Wars-inspired ‘tractor beam’ uses light to capture, manipulate cells) MIT's tractor beam can make the new types of SASER systems possible. The tractor beam just hovers the nanoparticle in air or medium, and then the laser or some other electromagnetic system transports oscillation into those particles. The ability to make cells and other particles hover in the system makes it possible to create particles whose energy level or resonance frequencies are accurately calculated things. That thing makes it possible to create things that transmit wave movement accurately and cleanly. This is one version of the use of a tractor beam. Modern tractor beams are like acoustic tweezers where sound waves lock the object in its cr

The new observations tell that the thunderstorms form gamma-rays. That could make gamma-ray lasers possible.

That could make gamma-ray lasers possible. The process has been observed by the NASA (Lockheed) ER-2 research plane, which is a modified U-2 spy plane. The gamma-ray formation in thunderstorms. Where lightning and electric fields release electrons that impact the air molecules and water droplets is an interesting thing. That thing opens the route to solving many mysteries. "The general physics behind how thunderstorms create high-energy flashes of gamma radiation is not a mystery. As thunderstorms develop, swirling drafts drive water droplets, hail, and ice into a mixture that creates an electric charge much like rubbing a balloon on your shirt. Pos

Chinese innovations and space lasers are interesting combinations.

Above: "Tiangong is China's operational space station located in low Earth orbit. (Image credit: Alejomiranda via Getty Images)" (Scpace.com, China's space station, Tiangong: A complete guide) Chinese are close to making nuclear-powered spacecraft. Almost every day, we can read about Chinese technical advances. So are, the Chinese more innovative than Western people? Or is there some kind of difference in culture and morale between Western and Chinese societies? The Chinese superiority in hypersonic technology is one of the things that tells something about the Chinese way of making things. In China, the mission means. And the only thing that means is mission. That means that things like budgets and safety orders are far different from Western standards. If some project serves the Chinese communist party and PLA (People's Liberation Army) that guarantees unlimited resources for those projects. Chinese authorities must not care about the public opinion. If we th
