CPU chip lines, are tight-polarized single wave lengths being used yet?

P: 69
If some engineers in the field are reading this, and know that they are being used, then please report here.

CPU chip lines can be configured with a variety of processes.

Years ago, lasers could have been used, but it seems to have taken a while for manufacturing to do that.

Then lasers that were polarized (wide-polarized) were available. Kind of a sloppy polarization, like is viewed through "polarized glasses." Not really tight.

Then processes to make lasers that were tight-polarized were available. A more advanced process.

There is an process beyond tight-polarizing. It is in common college physics, right there. But, we can skip that for now. I am just asking about tight-polarizing being used.

That brings up the question:

Are those tight-polarized, lasers being used yet? It has been a long time that they have been around and common college physics covered beyond that at least 20 years ago.

Are, as it seems, the manufacturing of CPU chips (the processes) so inept or backward facing that they still use "stone knives and bear skins [ST quote]?"

Engineers, what are you hearing?
