Amazing, I've only been here a short while, hardly posted anything, and you know more about me that I do, you even know, for a fact, that I personally know nothing, for a fact, that I have never built any laser machine, or laser, though you only appear to be aware of the existence of RF or DC excited CO2 lasers.

So, don't try to be wiser than "specialists", that would be you of course, judging by your sig.
