Fingertip-size lasers can revolutionize information and stealth technology.

   Fingertip-size lasers can revolutionize information and stealth technology. 

Fingertip-size femtosecond lasers can make many things. Those lasers can act as information transporters in quantum and photonic computers. In quantum computers, each of those small lasers forms one qubit line in that system. Then binary system shares information with those qubit lines. And that thing makes it possible to create a lightweight quantum computer that can operate at room temperature. That thing makes it possible that maybe we see quantum laptops quite soon. 

The femtosecond laser can control light and photons with a very high accuracy. So that kind of system can used to send counter waves or counter photons that can deny radiation reach the surface of the protected object. It's possible that in the case of this kind of quantum stealth, the system just drives incoming light over the aircraft's body. This system simply drives incoming photons past the aircraft or ship. And then that system denies radar or visible light reflection from the object. 


"A breakthrough in laser technology has been achieved by miniaturizing ultrafast mode-lock lasers onto nanophotonic chips, using thin-film lithium niobate. This advancement paves the way for compact, efficient lasers with wide applications in imaging, sensing, and portable technology."

The idea is that the counter waves turn those incoming photons to travel over the craft. And that means they act like radar impulses, that slide over the stealth aircraft's body. Because there are no radar echoes that make aircraft invisible to radars. And femtosecond lasers can make it possible to make the same thing with visible light. 

Femtosecond lidars can also act as anti-steath systems. The short-term energy burst can detect the stealth structures. And that short energy beam doesn't alarm the sensors that should recognize that kind of active lidar or radar scanning. 

The femtosecond lasers have a great ability to observe things like what happens in living cells. Those femtosecond lasers can adjust the energy impulses that they make. With a very high accuracy. That allows to use of femtosecond-class lidar systems in nanomachines. Those nanomachines can see things that happen in living cells. The nanomachines or nano-size submarines can observe things like neurons acting when they are part of neural structures.

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

Iron Dome is one of the most effective air defense systems.

The Iron Dome is a missile defense system whose missiles operate with highly sophisticated and effective artificial intelligence. The power of this missile defense base is in selective fire. The system calculates the incoming missile's trajectory. And it shoots only missiles that will hit the inhabited area. The system saves missiles and focuses defense on areas that mean something. The system shares the incoming missiles in, maybe two groups. Another is harmless and another is harmful.  Things like killer drones are also problematic because their trajectories are harder to calculate than ballistic missiles. The thing that makes drones dangerous is that they can make masks for ballistic missiles. And even if those drones are slow, all of them must be shot down.  The thing is that the cooperation between drone swarms and ballistic missiles is the next danger in conflict areas. In the film, you can see how drones make light images of the skies. The killer drones can also carry LED li

The innovative shield that protects OSIRIS-APEX can also protect the new hypersonic aircraft.

"NASA’s OSIRIS-APEX spacecraft successfully completed its closest solar pass, protected by innovative engineering solutions and showing improvements in onboard instruments. Credit: NASA’s Goddard Space Flight Center/CI Lab" (ScitechDaily, Innovative Engineering Shields NASA’s OSIRIS-APEX During Close Encounter With the Sun) The OSIRIS-APEX probe travels close to the sun. The mission plan is to research the sun. And especially find things that can warn about solar storms. Solar storms are things that can danger satellites at the Earth orbiter. And the purpose of OSIRIS-APEX is to find the method of how to predict those solar storms. Another thing is that the OSIRIS-APEX tests the systems and materials that protect this probe against heat and plasma impacts.  The same technology. The researchers created for OSIRIS-APEX can used in the materials and structures. That protects satellites against nuclear explosions. That means this kind of system delivers information on how to prot
