The new tools are improving communication and microchip technology.

"Schematic of chiral terahertz generation and control: A femtosecond laser interacts with a patterned spintronic emitter, producing elliptically or circularly polarized terahertz waves. Rotating the emitter adjusts the polarization, while built-in electric fields—formed by charge accumulation at the pattern’s edges—control the amplitude and phase differences. Credit: Q. Yang et al., 10.1117/1.AP.7.2.026007" (ScitechDaily,Tiny Stripes Unlock Powerful Terahertz Control for Faster Data and Sharper Scans)

Terahertz radiation and laser technology can boost microchip technology. And robotics with communication. Terahertz radiation is non-ionizing. That means it doesn't disturb its environment like radio waves do. This makes it a suitable tool for miniature microchips. Terahertz communication doesn't cause electromagnetic turbulence the same way as some radio waves. 

And terahertz radiation doesn't interact with radio waves. That gives that radiation a very high accuracy in communication. Coherent terahertz radiation makes it possible to create a safe communication tool. The terahertz stripes can make the terahertz masers possible. And terahertz-radiation masers are tools that can make very highly accurate communication possible. 

Another interesting tool is the miniature laser system. That system can allow to making of new types of microchips. Things like drones can also communicate by using small lasers. Both terahertz-masers and miniature lasers can make it possible to create smaller drones than ever before. Those systems allow the drone to use radio-wave-based energy transmission. Those new drones can be like some kind of smoke that can travel in the air.

"A new solid-state laser produces 193-nm light for precision chipmaking and even creates vortex beams with orbital angular momentum – a first that could transform quantum tech and manufacturing." (ScitechDaily,Scientists Create Compact Laser That Could Revolutionize Chipmaking and Quantum Devices)

Miniaturized laser technology is a tool that can make miniature drones to fight against things like bacteria. Those drones can capture and analyze any bacteria that they see. Laser systems can cut the DNA into the wanted bites. 

Miniature lasers can cut the cell organelles and that system makes it possible for the system to cut things like molecules at certain points. The nano-drones can operate in the nanotechnology factory. They can carry proteins and other things into the right places. That is one way to think about the nanofactory. The nanofactory can be the tank where the chemical environment is very accurately controlled. 

The nanomachines swim in the chemically controlled liquid. Then they can carry DNA or other molecules at certain points in the structure. Those nanomachines can look like smoke when they operate in that environment. The advanced AI and quantum computers control that nanorobot swarm. The robot swarm can get its energy from light or some radiowaves. In that system, the normal light can give energy to the nanomachine's photovoltaic cells.
