“ is it more affective in cutting / etching these materials with a lower optical output power.”

Probably because it’s more likely to be absorbed.

On the other hand, absorption can’t be > 100%. So a longer wavelength laser an cut just as well for the same power as long as the mtls absorbs all the photons

“ This looks like a great HN comment, ”

Thank you. I thought it was rushed w/out the explanation that it deserves (it has fascinating implications about the lack of the color blue in nature). Also, I felt it came out as snarky or arrogant, which I didn’t intend. But I was juggling other things :S

Unfortunately, I’m afraid you’ll have to ban me. I’ve abused the site far too long but I also have no intention to expose myself w/ a profile (any user with a karma > 1000 is trivial to dox).

What does “Burn” mean?

Break the bonds of just about anything except fluorides and metals? Probably.

Deposit enough energy I locally heat the material above it’s auto ignition T? Well that’s a flux question
