Free Electron Lasers(FEL) look like the future of EUV lithography.
This is how most EUV light is made today:
A powerful laser hits tiny molten tin droplets thousands of times per second.
The droplets turn into plasma and release the extreme ultraviolet light used to print the smallest features on advanced chips.
It works, but it comes with clear limits.
The process creates debris that contaminates the mirrors, the usable power is restricted, and the overall energy efficiency is low.
A Free Electron Laser(FEL) takes a completely different approach.
It accelerates electrons to nearly the speed of light and sends them through a series of alternating magnets called an undulator.
As the electrons move through the magnetic field they emit clean, coherent EUV light.
No tin.
No plasma debris.
Higher power output. Better efficiency. Narrower spectrum.
And in the right design, one source can feed multiple lithography machines at the same time.
Those advantages add up.
Cleaner light means less downtime and lower maintenance.
Higher power means faster throughput and fewer stochastic defects.
Better efficiency means lower operating costs at scale.
The ability to supply several scanners from a single source changes the economics of a large fab.
China is also exploring this route. Research groups there have published designs and studies on energy-recovery Free Electron Lasers specifically for EUV lithography, seeing it as a way to move beyond the limits of current tin-based sources.
This is why many see Free Electron Lasers as one of the real long-term paths for next-generation chipmaking.
The current method got the industry here.
FEL looks like the technology that can take it further.
Honestly speaking, India's advancement in propulsion technology is very very underrated
There are not many Countries who possesses Indigenous Turbofan engine, indigenous Scramjet Or ramjet engine and indigenous Cryogenic Or advance engine, infact it's just US , China and India
