By "toasted", you mean "unevenly charred to a crisp", right?

That was awesome!

And did you say 50 AMPS?! What laser are you running that can take 50 amps, a CO2 laser?!

I've eaten one of those before! 10.6µm seems to facilitate toasting more effectively. No, the color of the marshmallow has nothing to do with it.

Yummy!
I will try that when i get my next laser =]
Will your next laser be 10W or more? You'll be there quite literally all day if it's not class 4.

Yeah, CO2 lasers burn just about anything because of the long wavelength - I had to "sharpie" the marshmallow with blue food dye so it would absorb enough light to start burning :p

I'm guessing it's not yet outputting the full 60W? Seems like at that power it would be able to torch anything - white or not! Does it do anything to white paper w/o putting a marker on it?

He said it was only running @ about 50A or so, I believe this diode can handle 90A or so :)
