Time crystals are materials that oscillate at a certain frequency. That oscillation pumps energy to light. Another thing. This time-based oscillation can make. Is to make photons jump between the walls of that time crystals. The oscillation sends wave movement into that jumping light or photons. Another way to increase the power of that jumping light is to make outcoming radiation increase its power.

The new photonic system can increase the power of light exponentially. Laser rays can cut the route of other laser rays and form shadows. 

Photonic time crystals and lasers can be the tools for new types of photonic computers and next-generation photonic technology. The laser rays can close the route of light. That ability makes it possible to create the photonic switches. The idea is that the crossing laser ray can cut the path of another laser ray.  

And that allows the system to cut the signal. That kind of system can be a revolutionary advance for photonic microchips. Photonic microchips are tools that can minimize errors in quantum computers' qubits. The reason for that is that. The electromagnetic fields in those microchips are weaker. Than in regular silicone-based processors.

The high-power light can also ionize the atoms. The ion system can be used in medical and other systems like plasma stealth. In medical technology, the ion system can send ions to the targeted cells. The idea is that ions can tunnel themselves through the materials. The nanomachine can put tiny magnets to targeted cells and their positive pole can pull ions to those cells. Same way tiny magnets can pull ions or plasma to the targeted aircraft. 

"A black line across a region of blue illumination is the shadow cast by a green laser beam. "(R. A. Abrahao, H. P. N. Morin, J. T. R. Pagé, A. Safari, R. W. Boyd, J. S. Lundeen) (ScienceAlert, Scientists Discover Lasers Can Block Light And Cast a Shadow)

The same effect can protect the spacecraft and aircraft against laser rays. 

Researchers noticed that photonic time crystals could increase the light power exponentially. They can operate in sensing, imaging, and communication. The ability to amplify light exponentially makes it possible to create high-power laser systems. And the same systems can turn laser rays out from the layer. 

If we think about things like "flat lasers" or layers that can form laser rays from any point the system wants that system can make it possible to turn laser rays out from the target. The idea is that the system creates counter radiation with the same wavelength as incoming laser rays. 

When the incoming laser ray is weaker than the defending lasers that system turns the laser ray out of course. This system can use things like iron powder that it shoots to the route of incoming laser rays. That dust sucks the power of the laser beam and then the counter laser system can turn it away. When an attack is over the magnet can pull that dust out from the orbital. The same system can also destroy incoming missiles. 

That kind of system will not form the light from emptiness. The time crystal can increase the power of light by pumping energy into trapped light. Or the system can use an outside wave that transfers energy into those jumping photons. 

That system collects light and then focuses it. The idea is this. The time crystals form the space or "chamber" where light or photons jump from the chamber's walls. When light jumps from the edge of the time crystal. Outcoming light waves increase those jumping light waves' energy. That effect can raise the light's energy level to very high levels. When we think about things like laser rays those systems can turn even laser rays away. 

The high-power light can be used for ionizing air. 

The high-power light can also ionize the gasses like air. That means the high-power photonic systems can be used in levitational systems that create ion cushions below the craft. Then the craft can levitate over the ground by pushing those ions. The system also allows developers to create very interesting aircraft solutions. 

The idea is that the aircraft ionizes gas at the front of its wings. Then magnetic system pulls those ions backward. That thing allows the creation of very highly advanced vertical take-off and landing, VTOL systems. Those systems make it possible to make airfields and airbases in the middle of the cities, and those aircraft will not disturb people. 

That thing can also be the tool for the plasma stealth systems. In those systems, there is a channel in the aircraft body and wings. The air will be ionized in those channels. Then the aircraft that flies below things like strategic bombers can pull the ion layer between them and ground radars. And, if the system can load a negative electric load to the target. That system can make it possible to pull those ions against targeted systems.
