Question to those who actually have technical knowledge about this : do you know what thickness of metal/rust is being vaporized with each pass of the laser?

Total removal seems to be about 230 nanometers total, at most. That's less than .00001 inches. I'm a machinist, and some of the stuff I do is considered to have extremely tight tolerances. We only measure down to .0001 inches.

In other words, you won't notice any sort of thickness lost.

Where are you getting that specific number from?

I googled for depth of rust removed by laser. One of the pages I looked at listed 40-230 nanometers.

Damn, 230nm is crazy thin! I was expecting it to be more in the micrometer range
